How does HE300-7200-F differ from HE200-7200-F?

Both are 6200 W, 48 V units. The HE300 line has an 8500 W PV input limit instead of 9000 W, a 98% DC/AC conversion efficiency figure, and is covered by a different CE certificate (the KEYS EMC file) rather than the UDEM LVD+EMC file.

Which certifications cover this model?

CE EMC certificate CKEYS251201016 and the GB 4943.1-2022 safety report BDL260706S002. It is not on the FCC or RoHS model lists.

Two efficiency figures — do not mix them

The HE300 line publishes a 98% maximum conversion efficiency (DC/AC). This is the inverter-conversion figure, and it is a different measurement from the 99.5% PV charge efficiency quoted on the HE200 line.

PV charge efficiency — the DC-DC efficiency of the solar charging stage. HE200: 99.5%. HE300: 98%.
DC/AC conversion efficiency — the inverter output stage. HE300: 98%.

Quoting "98% efficiency" without saying which stage is a common way to mislead. This page quotes each figure against its measurement.

APL and UPS input modes

The utility input has two voltage windows:

APL mode — 90–280 Vac. Wider window, tolerant of weak or unstable grid supply. Used where the grid is poor and the load is not sensitive.
UPS mode — 170–280 Vac. Narrower window, faster transfer, used where the load is sensitive and the grid is reasonably stable.

Setting the wrong mode for the supply condition causes nuisance transfers. Details are in the installation guide.

Sizing context

8500 W of PV input against 6200 W output. Panel wiring: 540–700 W panels at 45–55 V open-circuit, strung within the 60–450 Vdc working range, never exceeding 500 Vdc open-circuit.

Battery side: 48 V at 6200 W is around 130 A. Charge current must respect chemistry limits — 0.2C lead-acid, 0.5C lithium. The utility charge current ceiling is 100 A.
