How It Works

The high-voltage hybrid pairs the same all-in-one topology with a high-voltage battery link, so charge and discharge run at lower current and higher efficiency. This matters as storage grows: lower current means thinner cables and less heat, and the round-trip efficiency gain is real on daily charge/discharge cycles. Three-phase models suit larger homes and small commercial sites.

Structure & Composition

The HY-HV replaces the 48 V battery port with a high-voltage DC bus (typically 150–500 V) coupled through a dedicated DC/DC stage to the battery bank. The rest of the architecture — MPPT, DC link, transformerless bridge, transfer switch — mirrors the low-voltage range, with additional current sensing and isolation for the higher battery voltage and three-phase output options.

Selection Guide

  • Larger homes, three-phase sites and small commercial storage above 10 kWh where high-voltage banks shine.
  • Choose HY-HV for round-trip efficiency and thinner cabling on bigger battery banks.
  • Match the battery voltage platform to the inverter's DC range before purchase — mixing platforms does not work.

Frequently Asked Questions

Q

Why choose a high-voltage battery?

Higher voltage lowers current, reducing cable size and heat and improving round-trip efficiency — worth it above roughly 10 kWh.

Q

Can I mix LV and HV batteries?

No — the battery voltage platform must match the inverter's DC range; they are not interchangeable.

Q

Are three-phase models available?

Yes, the HY-HV range includes three-phase units for larger homes and small businesses.
