Matching a battery to a Deye inverter — HV vs LV

Which Deye batteries pair with which inverters: the high-voltage and low-voltage (48 V) families, and why the classes must never be mixed.

Updated 20 July 2026

Deye hybrids come in two battery-voltage classes, and a battery only works with an inverter of the same class. Get this wrong and the battery simply won’t commission — the inverter’s DC window can’t reach it.

  • LV (low voltage) — 48 V nominal systems, battery window typically 40–60 V.
  • HV (high voltage) — stacked high-voltage packs, battery window from 160 V up to 700–1000 V depending on the inverter.

Never pair across classes. An HV battery on a 48 V LV inverter (or the reverse) is not a configuration problem — the voltage ranges don’t overlap at all.

The HV class is not limited to one inverter family — all three SG01HP3 / SG02HP3 ranges above are high-voltage, with different upper limits. Check the specific window for the model you’re quoting.

String inverters

The SUN G05 on-grid string range has no battery port — it’s PV-only. To add storage to a G05 site you either AC-couple a separate battery system or change the inverter; see AC vs DC coupling.

Before you order

Match the class first, then confirm the exact battery model is on the approved list for that specific inverter and firmware — the class match is necessary but not on its own sufficient. Check the inverter and battery datasheets, and for anything site-specific use the enquiry portal.
