Hey!
After a few weeks of researching, I've just found this forum and I'm hoping you guys can help me with your experience.
My plan is to take my country home off-grid. I'd like to have the capacity to power these items during longer days with full sun.
I'm considering 12v or 24v, whichever works best in the final setup. The panel(s) will be very close (within 2 meters) to the batteries and charge controller, etc.
Option 1:
Option 2:
(Both options need to be able to operate with a generator.)
I'm trying to choose suitable panels, I've found these and I'm wondering if they are compatible with 12v or 24v system.
Trina Solar Vertex S (mono)
Peak Power Watts-PMAX (Wp) 395
Power Tolerance-PMAX (W) 0/+5
Maximum Power Voltage-VMPP (V) 34.0
Maximum Power Current-IMPP (A) 11.62
Open Circuit Voltage-VOC (V) 41.0
Short Circuit Current-ISC (A) 12.21
Module Efficiency η m (%) 20.5
Maximum Power-PMAX (Wp) 298
Maximum Power Voltage-VMPP (V) 31.9
Maximum Power Current-IMPP (A) 9.32
Open Circuit Voltage-VOC (V) 38.6
Short Circuit Current-ISC (A) 9.84
I was originally considering purchasing four Renogy 100w panels but then I came across this 395w panel, which was much less expensive. Can anyone suggest why it's so much cheaper?
Which system option would be most value for the cost?
Thank you in advance for all input, I'm very new to all of this!

- Lighting
- Charging computers, phones, tool batteries, etc.
- Fans
- Energy efficient fridge and freezer.

Option 1:
- 395w panel(s)
- Renogy Rover 40 Amp Mppt
- 100ah LifePo4 battery (possibly 2 batteries)
- Inverter 2000w
- LifePo4 battery charger
Option 2:
- 395w panel(s)
- Mpp Solar mppt 24v 3000w
- 2 x 100ah LifePo4 batteries
