From grid tied to hybrid solar upgrade
| Answer pending
We have a 10.3kwh system. 26 panels on 2 lines. We have a grid tied solaredge inverter (se10000h-us) . We have a renogy lycan 5000 battery. If the power lines go down we want to power a subpanel and charge the battery. If we power the panel and plug in the battery i think we need to replace the inverter or get a second one. If we power the battery and let that power the subpanel i think we need a bigger charge controller.
I would like to buy the box that has the longest time to failure. Plus I’d like to keep costs down.
How do i find out what size of inverter I need? And how do i find out what size charge controller i need?
Thanks.
