Frequently Asked Questions

The Axpert MAX-6500-48-120 is rated 6500VA/6500W continuous, with 15000VA available on surge for the second a motor or a compressor starts. Size the load you actually intend to run against the continuous figure, never against the surge one.

The Axpert MAX-6500-48-120 takes up to 8000W (4000W x 2 of PV array. The string has to stay below 250 VDC open-circuit — that ceiling is reached on a cold bright morning, not at noon.

The Axpert MAX-6500-48-120 works with a 12 VDC ± 5%, 100W bank. It charges at up to 120 A, and that current — not the bank's capacity — is what the cabling and the fuse between bank and unit have to be sized for.
