Questions about this product

Can I use this module on its own?
No. This is a battery module that belongs to a matching system of the same brand: you also need the inverter or controller from that series. Not sure whether it suits your installation? Call or WhatsApp us on +31 10 261 33 86 with the brand and type, and we will check it free of charge.
Does this system need to be connected by an installer?
Yes. A fixed home battery is connected to your electrical panel, and that is a job for a certified installer. In the Netherlands and Belgium, you can request an installation quote from us; you will then receive a fixed date and the name of the installer in advance.
Does this work with my existing solar panels?
In virtually all cases, yes. Whether your current inverter can stay or needs to be replaced differs per system. Send us a photo of your electrical panel and inverter and we will check it for you free of charge.
How much energy does this module store?
The module has a capacity of 3.8 kWh, of which 3.65 kWh is usable (LiFePO4, 96 V). An average Dutch household (2,430 kWh per year, Milieu Centraal) uses around 3 to 5 kWh in the evening and at night; you can use that to estimate how much of your consumption this covers.
Can this module be installed outdoors?
No. This model's protection rating is IP21, so it belongs indoors or in a dry shed. Operating temperature: -10 to 50 °C.
How long does the battery last?
Lifespan of this model: 10,000 charge cycles. The warranty is listed in the specifications.
How much warranty do I get?
