There has never been a better time to convert your RV to solar power. Going mobile into remote places, there are no hook ups for easy power. Solar Can provide your basic needs. And the price of solar has dropped to the point that it is easy to afford.
First things first
The most important thing to consider before self-powering your RV is energy efficiency. Every light bulb should be replaced with LEDs. All appliances should be selected for low power consumption. Anything that heats should be propane. It will cost less to replace energy efficient items than to power them with a bigger energy system
Most boon-dockers use battery systems to power their essential needs. But they need to run a generator for the recharge the batteries. And to run larger appliances, the generator has to run all the time. This takes fuel and usually requires multiple fill-ups per day. And generators are noisy, possibly spoiling the whole reason for going remote.
A couple of solar panels, either hard mounted or setup when stopped, can recharge these basic battery systems. The typical system uses a charge controller between the battery and the panels. The charge controller disconnects the solar panels from the battery when they are full and at night. You are still limited to powering DC items.
Making AC power
The next step up is adding an inverter. Inverters take DC power, say from batteries, and convert it to AC power. This AC power, if the inverter is large enough, can power most of your AC needs, for example air conditioning. The issue with powering everything is the limit of the number of solar panels and the size of the batteries.
Getting it all together
What would be best is something that combines the best of each of the above. Solar to power DC and recharge batteries. An inverter to cover AC needs. And a generator for the times you need full power.
Tetra West Technology make Mi-Grid, a hybrid energy system. It combines solar panels, battery storage, inverter systems and a generator, all controlled by their patent pending energy management system. Solar panels supply DC power and recharge batteries during the day. The energy management system contains an inverter to power most of your AC appliances. And the automatically controlled generator starts up for large appliances and to re-charge the batteries if they get low.
And Mi-Grid is more affordable than you might think! Systems start at $4495 and include inverter / energy management system, high quality/long life deep cycle batteries and the automatic start generator. Solar panels are selected based on the configuration of your RV. Many models are available to match your needs.
When you’re out with your RV, playing with the generator is not top of the priority list. Mi-Grid allows you have full power, without the inconvenience of daily filling and weekly oil changes. Besides being messy and time consuming, the environmentally minded have to store the debris for proper disposal.
Compared to running a generator alone, a typical Mi-Grid system reduces run-time and fuel consumption up to 90% or more. Generator refills become weekly events instead of multiple times per day. Reduced run reduces oil change, sparkplug and other maintenance activities, letting you enjoy your RV more. Finally, reduced run time extend the life of the generator. A Mi-Grid system can pay for itself in a little as 90 RV days!

People living in the city are most likely to be familiar with the new trend of food trucks and their tasty fare, even though they have actually been around for years. With increasingly more people turning to the food truck industry for a cheap, quick meal and even at times a gourmet meal, patrons want a gourmet atmosphere. Emissions and noise from these gas guzzling generators can ruin that impression.
How can we now keep the power on our food trucks, while cutting the environmental impact?
The simple answer is to go solar. A lot of food truck vendors have discovered this, and are presently taking their local, sustainable and organic food job to the next level by using solar power. They aim to bring tasty, fresh, healthy and affordable food to the masses, and they are a more eco-friendly choice compared to several other fast food options.
Food trucks with solar power are presently taking a lead for several different reasons. A few include:
They are Cost-Saving
For many food truck operators solar is a cost-effective source of power. An average food truck owner operating on a traditional generator spends a minimum of $5 to $10 daily on fuel. There is also cost, labor and hassle in maintaining a generator. And the cost of replacement or repairing generators down the line can be costlier than installing solar panels. For a food truck operating 50 hours a week, the time for pay back can be as short as 9 months!
Traditional Food Trucks pollute the environment
The majority of food trucks operate on a diesel or gasoline generator that is specifically designed to run only a few hours. Operators tend to run them at a stretch for up to 14 hours, resulting in a high output of greenhouse-gas emissions, particulate matter, nitrous oxide and carbon monoxide. And the worst pollutant, is NOISE!
Considering the harmful effects, and the way solar power can offset operating costs, it is not difficult to see why solar food trucks are trending to solar. For more details on adding solar to food truck, contact [company name]
Several individuals have always considered off the grid and air conditioning never to belong in the same sentence, suggesting that you cannot have air conditioning off the grid.
The general response has been NO. Reasonably priced Off- grid solar power cannot run Air Conditioning. They are not powerful enough or the cost of a system is too great.
Mi-Grid is different. Mi-Grid is a hybrid solar energy system, combining battery storage PV solar with a backup generator. Even the smallest Mi-Grid can operate an Air Conditioner. The inverters and generators are sized to be able to start and run appropriately sized units. A tiny Mi-250 can run any 15 amp 110VAC window unit or even a 15,000 BTU/hr RV air conditioner. A Mi-Grid 4000, can run two 5-ton Air Conditioners with properly installed soft-starters.
The BEST choice for Air Conditioning is always a Mini-Split or inverter drive air conditioner. They require little startup power and are extremely efficient, reducing the amount of energy used for cooling. For the smaller Mi-Grid units, choose a 110VAC unit. For the Mi-Grid 1000 and up, 220VAC units can used.
Standard window air conditioning units can also be a good choice for the smaller Mi-Grid systems since they are 110VAC. Usually these are installed in bedrooms or small areas. 110VAC units work great with an essential circuits Mi-Grid. Get the most efficient one you can afford. Again, a mini-split is always best for your “essential” room.
Large whole house type Air Conditioning units can work with larger Mi-Grid units, especially with the addition of a small A/C soft start unit. The normal problem with running Air Conditioners is the power needed for startup. It can be as much as 5 times the operating power. A properly installed soft starter limits the starting power to only 50% over running power. This means a smaller inverter or generator can startup a larger air conditioner. And as always, get the most efficient one as possible.
One type of air conditioner/heat pump works extremely well with whole house Mi-Grid systems. Geothermal heat-pumps circulate coolant into the earth where year-round temperatures are far more moderate. This allows the heat pump to work much more efficiently and use much less power. Some of them have SEER’s between 40 and 50!!!
Mi-Grid can also be setup to provide power to all your essential circuits and outlets. High power circuits, for example air conditioners, are setup to only run with the generator. This allows the comfort of air conditioning while minimizing generator operation.
One final note: Insulation and shade. The cheapest way to keep cool is to not get hot in the first place. A shaded home/RV will use much less power. The more insulation, and the higher R-value insulation, the less heating or cooling you will need. And finally, cook outside in the summer. The less heat you add, the less air conditioning you need. Solar doesn’t work in the shade, but potable solar panels or ground mount arrays, can be placed in the sun with your house or RV in the shade.
You don’t have to give up comfort off-grid. Mi-Grid provides the power for everything.
Solar panel systems are powering virtually anything you can imagine and most likely a number of other systems you were not even aware existed.
Presently, solar powered lighting systems are utilized for illuminating Streets, secured storage areas, Parking lots, pathways, business roadside signs and traffic control lights.
Offering both decorative accent lighting and functionality, solar lighting can now be used with motion sensors so that the light source switch on itself whenever they are triggered by intruder’s movement or visitors. And now, stairways and pathways that use to be dark in the evening can be lighted with solar lighting systems. Furthermore, a number of communication firms are making use of solar-powered systems with battery backups to power their communication towers in remote locations. In addition, solar powered systems that are coupled with battery backup systems enable homeowners to power their remote locations that are off-grid. Clinics and hospitals as well utilize them for emergency power backup systems, security alarm systems and medical refrigeration systems. Solar powers are also used for water well pumps in remote locations where power is not considered for grid supplied, businesses and homes. As a matter of fact, the use of solar power systems can only be limited by your resourcefulness and imagination.
Some cities across the globe are even making use of solar powered trash bins which compact the trash on scheduled time periods making better use of the capacity of these trash bins and reducing the frequency with which they need to be emptied again thereby saving thousands of dollars yearly in hourly personnel wage costs. Solar power can likewise be used to recharge gadgets from your mobile phones to laptops and it comes in a wide range of packages from handheld devices to backpacks with solar modules built into their clothing.
It is no longer news that solar energy manufacturers are making more modern devices that can be used daily and by so doing, enabling us to tremendously lower our reliance on the conventional carbon fuel produced electricity. Although these newly-developed devices and systems will come with a higher rate to cater for their R&D expenses, with the prices for solar modules already falling, it is not different from buying that new LCD TV set when it first enter the marketplace with the exception that these systems will save you money in the long run and ought to be taking seriously into consideration for your use and purchase.
Mi-Grid is a hybrid solar energy system, combining battery storage PV solar with a backup generator. It can provide for all of your power needs, on-grid or off-grid, stationary or mobile, on-shore or off-shore. It can provide your power in times of emergency.
Mi-Grid can provide power two ways. Standard Mi-Grid systems are primarily solar powered. The solar PV panels collect power during the day. What isn’t used is stored in the batteries for use later. The solar is designed to provide average power needs, year-round. The generator provides backup power, in cases of low sunlight or a day of very high energy use.
The generator is sized to recharge the batteries only if they become discharged, running long enough to recharge and providing power at the same time. Generator control is automatic and switching is so fast you may never notice. Even using Air Conditioning in the summer, an appropriately sizes Mi-Grid will use about 1 hour of generator time per day. Some days more and some days, none at all. These Mi-Grids are designed to provide all day power, even Air Conditioning, at all times.
The other way Mi-Grid can work is to provide a smaller Mi-Grid system but a larger generator. Sometimes it is not possible to provide a full size Mi-Grid. This could be due to available space for solar panels or even cost issues. A small Mi-Grid provides essential power at all times and the generator powers larger systems as needed.
The electrical system is split into essential and intermittent. The essentials are powered by Mi-Grid’s inverter output. They never lose power. Intermittent systems are only provided power when the generator is running.
Essential systems include small 110VAC air conditioners, microwave oven, toaster over, small appliances, TVs, lights and ceiling fans. Basically, anything that is 110VAC. Depending on the size of the Mi-Grid, care may be necessary with what is run together. But most day to day items work are fine. For a regular house, small mini-split or window A/C units can be run at night in the bedrooms.
Intermittent systems include large 220VAC air conditioners, 220VAC appliances, electric stoves, electric ovens electric dryers and electric hot water heaters. With a larger Mi-Grid system, some of these systems could be placed in the essentials area. A manual switch is provided to start and stop the generator when the intermittent systems are desired. Mi-Grid still can start the generator if the batteries become low. And the intermittent systems can be used anytime the generator is running.
The Mi-Grid 250 and 500 are 110VAC. You have to use to generator for 220VAC systems. With the Mi-grid 1000 and up, 220VAC appliances can be in the essentials.
