I am looking to build something like the https://www.mobile-solarpower.com/2000-watt-24v-solar-system.html
I don't have a need for a 24 to 12 volt appliances.
I plan to build this for off-grid, in case power goes down and to use it occasionally for fair weather outside use.
Are my numbers correct for four panels to this MPPT? It seems close.
I am just planning to change the panels to
Panasonic Evervolt EVPV360K 360 Watt panels. It seems like I can use four of these.
With the remaining components as described on the website above (except the DC converter).
Rated Power (Pmax)¹ 360W
Maximum Power Voltage (Vpm) 36.7V
Maximum Power Current (lpm) 9.82A
Open Circuit Voltage (Voc) 43.9V
Short Circuit Current (lsc) 10.49A
Temperature Coefficient (Pmax) -0.26 %/°C
Temperature Coefficient (Voc) -0.24 %/°C

- 40 amp MPPT charge controller with over-current protection
- EPEVER 40 Amp MPPT Solar Charge Controller 150V PV Input Negative Ground
- 2x or 4x 12v,100 ah LiFePO4 Batteries (wire these 4x batteries in series/parallel to create a large 24v battery bank)
- Initially, I was thinking to not use batteries, but I think I would need a different MPPT, correct?
- 1000-3000 watt, 24 volt inverter
- Battery Protect by victron energy, 100 amp
- 4 gauge copper wire and lugs/heatshrink
- 50 amp circuit breaker for the MPPT, 25 amp fuse for the converter
- Wooden board to mount the components
