Sungrow’s PowerHarbor residential ESS is now commercially available in the Netherlands, Belgium and Luxembourg
It can be added to an existing PV system while retaining the installed inverter, or installed as a hybrid replacement for that inverter
The system pairs with the EnergyBridge backup gateway, which integrates 5 functions and occupies up to 99% less volume than conventional alternatives
PV inverter and energy storage system (ESS) supplier Sungrow has made its PowerHarbor residential ESS commercially available in the Benelux countries of the Netherlands, Belgium and Luxembourg.
The all-in-one system combines a 3-phase hybrid inverter, measuring 788 mm × 375 mm × 255 mm, with stackable lithium iron phosphate (LFP) battery modules. Each battery module measures 788 × 280 × 255 mm and incorporates battery management and pack-level optimization. The Benelux range covers inverter outputs from 10 kW to 15 kW and 6, 9 or 10 kWh battery modules, allowing 83 system combinations, according to Sungrow. Customers can add new battery units alongside older units. Sungrow says the system switches to backup power almost immediately after a grid outage and can supply up to 15 kW of backup power.
For retrofit projects, PowerHarbor can be installed as a separate battery system without replacing the existing PV inverter or other balance-of-system equipment. Alternatively, the existing inverter can be replaced with PowerHarbor’s hybrid inverter. Its PV input has a 100 V starting voltage and a maximum power point tracking (MPPT) range of 100 V to 950 V.
Sungrow uses blind-mate connectors between the battery modules and inverter, which it says allow electrical connections to be completed in about 10 seconds. The system can be opted with external backup gateway – EnergyBridge – that integrates a changeover switch, circuit breaker, meter, bypass switch and current transformer (CT). Sungrow says it occupies up to 99% less volume than conventional arrangements using separate components.
PowerHarbor supports PV-to-battery charging at up to 160%, allowing surplus PV output that would otherwise be clipped to charge the battery. A discharge rate of 0.66P allows the battery to discharge its usable capacity in about 1.5 hours. Sungrow says the system can connect to up to 28 virtual power plant (VPP) platforms. The 10 kW and 12 kW inverter models also support 3-phase unbalanced loads of up to 150% of rated output.
The launch comes ahead of the Netherlands ending its net-metering scheme on January 1, 2027, which will increase the value of consuming more solar electricity on site or storing it for later use.
