Sigenergy inverter: models, prices and home battery alternatives
Sigenergy supplies hybrid inverters (SigenStor series) from 6 to 20 kW. We don't currently sell Sigenergy home batteries; see our inverters below plus the closest-matching home battery alternatives by capacity.
What does a Sigenergy inverter cost and does it work with a home battery?
Sigenergy inverters cost between 1,331 and 4,013 euro including VAT here. We carry 6 Sigenergy inverter models. Which batteries are released for a Sigenergy 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. Sigenergy batteries sit at 452 euro per kWh, about 38 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.
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
Sigenergy inverters cost between 1,331 and 4,013 euro including VAT here. We carry 6 Sigenergy 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 Sigenergy 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. Sigenergy's own batteries sit at 452 euro per kWh, about 38 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.
