Home Backup Power

Everything for a house that stays on when the grid goes down: complete backup packages, the Growatt MIN and SPH hybrid inverters, APX, ALP and GSL batteries, and the transfer switches and backup interfaces that tie them into the service panel.

If you want one matched package, start with the partial-home and whole-home backup systems. If you are building around an array you already have, pick a MIN TL-XH-US inverter sized to it, add APX battery modules in 5 kWh steps, and the SYN 200-XH-US or ATS-XH-US to switch the house over.

Size the battery to the loads you need through an outage and the hours you want to ride through, and size the inverter to the largest of those loads running together. The finder above sizes it from your loads, or send us your panel schedule and we will spec it. Installation is by a licensed electrician, and grid interconnection is approved by your utility.

Not sure which one? Tell the finder what you need to run and it sizes a system from stock, with the reasoning shown.
