So I'm looking at putting PV on the roof with battery backup.
I'm in Australia so we are limited on what we can use here and I'm having trouble finding a suitable Hybrid Inverter.
My wish list include;
- 3 phase 10-15kW
- Whole house UPS (<20ms failover from grid to battery)
- Support for 48v...
How did you go with this?
I would have thought that 2xSPH5000 would do the job.
That gives you 10kVA of output and up to 170A of battery charging (8000W).
Most 48v LiFePO4 batteries can support up to 100A so you would probably want to run at least 3x5kVA batteries in parallel.
