Frequently Asked Questions

The ESS510 5.5KW takes up to 6500W of PV array.

The ESS510 5.5KW works with a 51.2VDC bank. It charges at up to 50A (0.5C), and that current — not the bank's capacity — is what the cabling and the fuse between bank and unit have to be sized for.

Peak efficiency is 96%. Whatever is not converted leaves as heat, so the ESS510 5.5KW needs clear air around it and a mounting spot that is not the hottest wall in the building.
