Looking for some ideas on how to achieve an extension/upgrade to an off-grid system.
3 years old.
Fronius primo 8.2
DC and AC coupled system.
8x BYD B-Plus 2.5 (20kWh total)
We wish to increase the battery capacity however stock of the same type is hard to get. Don’t wish to replace original batteries at this stage.
Also wish to increase the solar, no issues there.
Open to adding another Quattro and therefore having higher power available in the system, along with a new additional battery bank, additional MPPT and extra solar.
Is this our only option, or there any other methods of adding capacity we should consider?
