I have a solar-off grid system that is powering DC loads only and the system is as follows:
- MPPT 250/70
- 3540 Wp Solar PV
- 48V 200Ah Battery Bank
- Cerbo Gx
- VE-Bus-BMS-V2
How can I add a back-up generator to this system that starts automatically only when the solar power is not sufficient? (Note: My loads are all AC so I don't need an inverter in my system)
Please support.
Here is my system wiring diagram: Wiring Diagram (R1) .pdf
Thank you.
