Sunwoda has modified the battery (BAT) connector on the SunESS system. Consequently, earlier units are not compatible with currently shipped models. To distinguish between them, we are marking the new versions with "S1" in the product name.
This additional BMS is required for system configurations with more than four storage modules. In such cases, the storage modules must be set up as a second tower.
As one of the world's largest cell manufacturers, Sunwoda Energy’s technology is already found in many well-known products. With the SunESS all-in-one system, the company is now stepping into the spotlight to compete directly in the residential market. The hybrid inverter and storage modules form a cohesive, visually appealing unit. The power classes—ranging from 8 to 15 kW—are practically designed and equipped with all necessary interfaces. Input currents of up to 30 amperes and integrated Type 2 surge protection ensure safe and flexible application options. The 5 kWh storage modules can be cascaded up to eight units deep. The backup connection ensures the reliable operation of sensitive loads with a switchover time of less than 10 ms.
