Off Grid 3.7kW Solar Power System
Looking for an off grid system that will power your cabin, home, or other remote location? Look no further. altE has designed several kits that give you the option to choose the best sytem for your needs - whether you're looking for a roof mount system, a ground mount system, or a pole mount system, or if you have a preference of a battery technology for your energy storage. There is also the option of adding wind power to your off grid system, for a hybrid alternative that complements solar perfectly. These kits are designed to provide you with most everything you need to go off the grid. The performance of each off grid solar power system will vary greatly based on the location where it is installed. See the map below to see the solar potential in your area. And, if you need help sizing a system for your off grid home, start by checking out our Off Grid System Calculator.
How much power will I get from this system?
Find your location on the Map. This map shows the amount of daily power, in hours, received each day, on an optimally tilted surface during the time of year when there's the least amount of sun.
Base Components of this Off Grid System:
The solar panels and the pre-wired inverter/charge controller system and components are included in the base kit. Battery bank and Mounting solutions are options that you can add on.

Let's start with Solar Panels:This 3.7kW off-grid residential home solar system features twelve (12) Peimar 300 Watt Solar Panels. PEIMAR solar panels made in Italy provide customers with a perfect combination of high-efficiency and versatility. Thanks to the use of high-quality solar cells, these solar panels achieve outstanding performance and ensure maximum production output even under poor lighting and weather conditions. The strong yet ultra-light frames, make installation easy. These panels provide a robust installation in either residential, commercial or large-scale settings.
**Even though the image above shows poly modules, this system comes with mono solar panels as listed in the table.
Next we need the Inverter and Solar Charge Controller System:
The inverter in a renewable energy system will convert the DC power from the solar panels to usable AC power for your home. The charge controller does several things, most importantly keeping your batteries from overcharging, and an MPPT charge controller will allow your solar panels to operate at their optimum power output voltage, improving system performance by up to 30%. In this kit, altE Pre-Wired Inverter System takes the guesswork out of installing a battery based inverter system, saving you valuable time. With a pre-wired solution, the confusion is taken out of selecting all the right parts. This system uses the Schneider Electric Conext SW 4048 Inverter/Charger that is rated at 4,000 watts and uses a 48 volt battery. It produces 120/240 volts AC. The Conext SW is a convenient combination of an inverter, multi-stage battery charger, and transfer switch in one electronic device. The Midnite Solar Classic 150 MPPT Solar Charge Controller is the only MPPT charge controller with both ground fault and arc fault protection built in, providing the greatest protection for your system. And it's made in the USA!
