GivEnergy 20kW 3-phase HV hybrid inverter

Larger three-phase sites are where this inverter earns its place: a 20kW HV hybrid unit built for commercial premises and big domestic loads that a single-phase supply cannot serve. It manages generation, storage and grid across all three phases from one box.

Description

This is the top of the three-phase HV inverter line, sitting above the 10kW and 11kW units for projects where the demand profile genuinely needs the headroom. It works with high-voltage battery towers rather than low-voltage packs, so the DC side is designed around HV modules from the outset. Specify it when the load calc points at 20kW and the site already runs three-phase. Ordering is the trade way here: the ex-VAT price on this page is what your account pays, drawn from UK stock and rebuilt as the feed refreshes.

What it pairs with

On the DC side it takes GivEnergy HV battery modules such as the 3.4 kWh HV pack (GIV-3.4KWH-HV-BATT), stacked with their matching HV top box to reach the working voltage. For remote data, add the GivEnergy Data Collector dongle. Sibling three-phase HV inverters are the 10 kW and 11 kW units. Because usable battery counts move with model and firmware, confirm the stack against GivEnergy's current three-phase HV pairing list.

Three-phase supply required; this unit will not run on a single-phase connection. High-voltage battery modules only, not low-voltage packs. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

GivEnergy GIV-3P-20KW-HV buying questions

The ex-VAT trade price is shown on this page, and VAT at 20% is added on the invoice. That rate holds whether you take a single inverter for one job or several for stock, because there are no minimum orders and no annual-spend tiers. Every trade account sees the same price for the same part.
As an inverter rather than a battery, it ships by parcel courier, so no special freight arrangements apply. Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment. Stock is held on consignment and confirmed on enquiry rather than shown as a live count, so ask if you need a firm figure before ordering.
Stock on request at the last catalogue update, and the count on this page comes from the live stock feed rather than a manual list. In stock means in stock; if the number reads zero, the trade desk can tell you the restock position for this part number.
UK trade buyers with a verified account: limited companies verify with a Companies House number, sole traders with a UTR, MCS or scheme number. No trade minimums — one unit at trade price, no annual-spend tiers.
