A high-voltage battery must sit inside the inverter's battery voltage window. The HV PACK stacks 5 to 14 packs per string, from 288V (HV PACK 5) to 806.4V (HV PACK 14). BSLBATT matches the HV PACK configuration to the chosen inverter model before quotation, so send the inverter model with your project details.
This wide range lets one product serve homes, schools, hospitals and small factories. Lower pack counts give a lower system voltage for smaller single-phase inverters, while higher counts serve larger three-phase sites.
Does the ESS-GRID HV PACK work with single-phase high-voltage inverters?
Yes. BSLBATT supports the HV PACK with single-phase high-voltage inverters. Listed brands with single-phase HV models include Solinteg (MHS-3-8K), SAJ (H2 series) and Solis (S6 series). The pack count sets the system voltage, so BSLBATT matches the configuration to the inverter's battery input range.
