Product Introduction Soluna’s S8 EU-A50 can connect with a solar power generation system, assisting the customer to use environmentally-friendly energy 24 hours per day. The BESS can store the energy generated by the PV, using it when required, reducing electricity bills, improving the household energy self-consumption and working when there is a BLACKOUT.
Working modes Soluna’s S8 EU-A50 have the working modes (see below): Mode 1: In the daytime, the PV power will charge the battery as a priority, if the battery is full, the PV power is used to power the loads, then finally excess energy is sold to the Grid.
Active power and reactive power setting The Soluna BESS is capable of producing reactive power and feeding it into grid through the setting. Feeding in management can be controlled directly by the grid company through a dedicated communication port. Volt-Var Response Mode The Soluna BESS series complies with AS/NZS 4777.2: 2015 standard which introduced the voltage-var response mode to restrict the power output of the inverter in response to the voltage at its terminals (refer to AS/NZS 4777.2: 2015).

Volt-Watt Response Mode The Soluna BESS series complies with AS/NZS 4777.2: 2015 standard. The grid voltage at which the inverter output starts to drop/de-rate is set to 250 V by default as required by the standard. This means that when the grid voltage exceeds 250 V, the maximum output of the inverters will be restricted (as required by the standard).

Remark: User can find the QV & VM icon in reset & advanced setting icon on the LCD), Please find the following picture for details. DRMs, logic interface for AS/NZS 4777.2:2015, is used to receive and response commands from grid company and then adjust inverter output power. The Earth fault alarm Before the inverter starts to connect to the grid, the inverter will first detect the impedance of PV + to ground, and the impedance of PV- to ground.
