Solax inverter: all models and prices

Solax X1 and X3 Hybrid inverters combine solar panels with a home battery, from 3 to 10 kW. Compare all Solax inverters we supply below, incl. VAT and manufacturer warranty.

What does a SolaX inverter cost and does it work with a home battery?

SolaX inverters cost between 270 and 3,372 euro including VAT here. We carry 34 SolaX inverter models. Which batteries are released for a SolaX inverter is listed in our compatibility table of 544 manufacturer-approved combinations, each row naming its source document. A combination that is not in there is not approved, even if the voltage matches. SolaX batteries sit at 372 euro per kWh, about 13 percent above the Dutch market median of 328 euro per kWh.

A hybrid inverter is required as soon as solar panels and a home battery have to work on the same system. Voltage and communication protocol both have to match, or the battery will not charge even if the connectors fit. On a three-phase connection choose a three-phase inverter too, otherwise you can only export on one phase. Installation belongs with a certified installer, who wires it into the consumer unit and registers it with the grid operator.

Net-metering ends on 1 January 2027

From that date the feed-in credit for solar power largely disappears. A home battery lets you use more of your own generated power yourself, including in the evening, instead of exporting it at a low rate.

Frequently asked questions

SolaX inverters cost between 270 and 3,372 euro including VAT here. We carry 34 SolaX inverter models. Price mainly follows the power rating and whether the model is hybrid: a hybrid inverter can drive a home battery as well as solar panels, and therefore costs more than a string inverter of the same rating.

Only the hybrid models can drive a home battery; a string inverter only converts solar power for direct use and export. Which batteries are released for a SolaX inverter is listed in our compatibility table of 544 manufacturer-approved combinations, each row naming its source document. A combination that is not in there is not approved, even if the voltage matches.

The release list decides that, not the price. Start from the combinations the manufacturer has approved and compare those on price per kWh. SolaX's own batteries sit at 372 euro per kWh, about 13 percent above the Dutch market median of 328 euro per kWh. The same model costs a median 22 percent more at the dearest Dutch shop than at the cheapest, so comparing on model number usually pays better than switching brand. The middle half of all Dutch offers sits between 249 and 424 euro per kWh.

Yes, if you want to export and discharge across all three phases. A single-phase inverter on a three-phase connection does work, but you then export on one phase while the other two keep drawing. Whether that costs you anything depends on how your meter nets across phases. From roughly 5 kW of inverter power, many Dutch grid operators require three phases anyway.

A string inverter converts direct current from the solar panels into alternating current for direct use and export, and does nothing else. A hybrid inverter also has a connection and a control loop for a home battery, so surplus goes into the battery first and onto the grid only afterwards. If you want to add a battery later without replacing the inverter, choosing hybrid now is cheaper than swapping later.

Yes. An inverter is wired permanently into the consumer unit and registered with the grid operator, which is work for a certified electrician under NEN 1010. We supply the hardware; installation you arrange yourself or through our installation partner on request. Wiring it yourself in practice voids the factory warranty and can affect your buildings insurance.

Where do these figures come from?

Every number on this page comes from one of our three open datasets. They are built independently of our own stock and cover brands we do not sell, so the measurement does not depend on what happens to be in our shop.

  • Dutch home battery price index Median 328 euro per kWh including VAT, measured across 1,020 offers at 61 Dutch online shops between 2026-08-16 and 2026-09-01. With medians per capacity class and per brand, and the full method including every exclusion rule.
  • Cell chemistry per model The cell chemistry of every home battery we sell, established per model, each row naming the manufacturer document it came from, plus the models rejected after checking.
  • Battery and inverter compatibility 544 manufacturer-released combinations of home battery and inverter, merged from official compatibility documents, each row naming its conditions and its source document.
