This above totals to 747W. 747 * 2 = 1494W. In this case, the SigmaPro3024 would be the ideal system by allowing load to be equal or less than 50% of inverter's rated capacity. Now, depending on how long you wish to run these devices will determine how you will build your battery bank. Download our worksheet here to plug in some numbers and try different configurations.
The SigmaPro 3024 is a 24VDC system, which means there needs to be two (2) 12VDC batteries connected in series for each set and we need 2 sets. This means the battery bank should be four(4) 200Ah 12VDC Sealed Lead Acid batteries, 2 wired in series and 2 wired in paraelle to achieve 400Ah at 24VDC. This will allow the above equipments to be running for 3 days on battery power only.
Our SP200W-18V solar panels are rated for 200W per panel with 11.2 Imp (max current rating). We take 15Ah/11.2 = 1.34 solar panels, this is the number of panels needed to keep loads running. We round up to 2, which means 2 sets of solar panels wired in parallel. When sun power is not 5 hours, we now have the extra panel space to compensate.
