The Fox ESS CQ7 is a modular high-voltage home battery with LFP cells. Each module has 7.02 kWh. A tower always consists of one master module (with the battery management system) and one or more slave modules, on a base. With two modules you have 14.04 kWh; with the Fox ESS H3 Smart inverter you can expand up to 12 modules (84.24 kWh).

You click the modules onto each other without separate cables in between. The housing is IP65, so the battery can also be placed outdoors, and it has a built-in fire protection module. Charging is possible between 0 and 55 °C.

This battery comes without an inverter. It works with the 3-phase hybrid inverters from Fox ESS, such as the H3 Smart. Please note: the inverter charges and discharges at a maximum of 50 A. With two modules (115 V) that is approximately 5.8 kW. For the full 10 kW of an H3-10.0-Smart you need at least four modules.

High-voltage system: installation by a certified installer.

How to connect it

  • Via a Fox ESS hybrid inverter3-phase with the H3 Smart (2–12 modules) or H3 Pro; 1-phase with the H1 or KH (2–7 modules). The inverter is not included with this battery.
  • By an installerHigh-voltage battery: connection to the inverter and electrical panel is done by a certified installer.
  • PlacementStanding tower on a base, 660 x 360 mm footprint. IP65, indoors or outdoors.
  • ExpandingPlace extra 7.02 kWh slave modules on top of the tower.

When 800 W and when full power?

The CQ7 delivers 50 A recommended and briefly up to 80 A. Because the voltage rises with each module, the power grows too: approximately 5.8 kW at 50 A with two modules, just over 11 kW with four modules.

How much power your home gets, and whether backup power is available, is determined by the Fox ESS inverter. The H3-10.0-Smart delivers up to 10 kW, also as backup power, and needs at least four modules for full power.

Questions about this product

Which inverter does the CQ7 work with?
According to the Fox ESS compatibility list, the CQ7 works with the Fox ESS inverters H1 and KH (single-phase, 2 to 7 modules), H3 Smart (three-phase, 2 to 12 modules) and H3 Pro (three-phase, from 4 modules). If you have an inverter from a different brand, please ask us first.
How many modules do I need?
At least two: one master module and one slave module (14.04 kWh). For the full power of a 10 kW inverter you need at least four modules, because the inverter charges and discharges at a maximum of 50 A, so the power increases with the battery voltage. Not sure? We are happy to work it out for you.
How big and heavy is the battery?
The tower is 660 mm wide and 360 mm deep. The height grows with it: 420 mm with 2 modules up to 1970 mm with 12 modules. The weight ranges from approximately 103 kg (2 modules) to 591 kg (12 modules); each additional module weighs approximately 49 kg.
Can the CQ7 be placed outdoors?
Yes, the housing is IP65 and the battery is designed for indoor and outdoor use (standing on a base). Charging works between 0 and 55 °C, discharging between -10 and 55 °C. In a location where it freezes hard, the battery therefore cannot charge in winter; a garage or shed is more practical in that case.
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.
What about the warranty?
You get the official manufacturer's warranty of the brand. Multi-Solar is an authorised dealer, so warranty claims are handled by us in Rotterdam and not via a foreign importer. Call or WhatsApp us on +31 10 261 33 86.
When will my order be delivered?
