Guys n Gals I need help with a small PV setup. I am planning to setup a small PV for my house. The list is as follows.
The panels will be 24 Volts and will be in series. The Batteries will be in 24 Volt (in series) and the Inverter also is 24 Volts. The weather is very hot in my region, summer easily getting above 35 - 40 degree C and winter is about 20 - 30 degree C.
My first question is, can I possibly add another panel to the system. Making it 3 panels (Voc= 37.5 * 3 = 113 Volts) which is higher than the rating of the CC. My argument is that the panels will never produce the said output due to a lot of factors aka losses. Would it be wise to use 3 panels? if the PV is of lower wattage (200 Watts) can 3 panels be used (Max. PV input power 780W)?
Secondly, the system will be utilized throughout the day 8AM-4PM. My Max. usage is 10.8KWh per/day but it will be near 5 KWh per/day (not everything is running all the time). During the night time the power will be from the mains but not charging the battery. The battery might be used for 1-2hrs at night when main electric fails.
Will the charging to the batteries be enough for the night usage and then charging in the day time?
Thanks
- Solar Panels 24V -- 2 x 250 Watt Monocrystalline (500 Watts). Voc = 37.5, Isc = 8 A,
- Charge Controller -- 30 A MPPT epsolar Tracer3210A.
- Local car float lead acid 200 Ah, 24 volts (2 x 12 Volt).
- 1500 VA inverter AC (980 Watts AC).
