18 Months with OFF GRID Solar – Worth It?

We’ve been off-grid on solar for a year and a half. Has it worked? Have we had to change our behaviour? Do we use more or less power than we used to? How much do we need to use a backup generator?

We’ll answer all these questions and discuss some of our future plans for upgrades and expansion.

Our Solar Setup:

  • 2400kW of solar panels
  • 3-string DC combiner box
  • Victron MPPT Solar Charge Controller 150V | 60A
  • Victron Multiplus II 48V | 5kVA | 70A inverter / charger
  • Victron Cerbo GX communications system
  • 4 Pylontech US2000 batteries | 9.6kWh of battery storage

Total system cost: €6250

MOSA GE-4000 3kVA generator | Honda petrol engine – additional €770

Solar Shop was the supplier of solar kit we used in Portugal (not sponsored)
