For my Off-Grid Solar System I have my Corrected watt-hrs per day…Now What?
*Note: Points to keep in mind when you are looking at the different systems:
1. Make sure the inverter is large enough to run your loads concurrently.
- take the highest AC loads in watts, Eg. 6000 watts Given inverters have a 50% surge rate, a 4000 watt inverter will work
- take the total AC connected wattage at one time. This must be lower than the inverter rating
2. That you have enough battery storage for 1 – 2 days, roughly 30% of total kW storage capacity.
- take your corrected watt-hrs per day, Eg. 5000 watts x 3.33 = the battery capacity you need, which in this case is 16,650 watts or 16.6 kWh
3. Solar array size required: given good southern exposure with no shading.
- take your corrected watt – hrs per day, divided by 3 sun hrs/day = the array size this is a good 3 season average number to divide by Eg. 5000 watts /3 = 1660 watts This is the minimum size solar array needed. If there will be shading, adjust accordingly. Using the above points and wattage examples, our Small Home Kit #2 would be a good system to install (providing there are only 120V loads).
OFF – GRID WARRANTY:
One (1) year on installation plus all our products include the manufacturers warranty which range from one (1) to five (5) years, and up to twenty – five (25) on solar panels. After one (1) year, we offer an annual service contract which will cover our labor and travel, all parts will be extra
