ESS sets with Solis 15 kW HV hybrid inverter and Pylontech Force H3 batteries (10.2–35.8 kWh)

Core of the system
The Solis 15kW high‑voltage hybrid inverter is a three‑phase unit designed for HV battery systems. It provides two to four MPPT inputs for multiple string orientations, supports unbalanced loads on grid and backup ports, and can be paralleled up to ten units. Its UPS switchover time of less than 10 ms keeps critical loads powered. Monitoring and firmware updates are handled via the SolisCloud app. The inverter incorporates AFCI protection and uses natural convection cooling. Additionally, it allows three‑phase unbalanced output up to 40 % per phase and a PV input ratio of 160 %.

The Pylontech Force H3 modular HV battery uses LiFePO₄ technology. Each 5.12 kWh module includes its own BMS; two to seven modules can be stacked (10.24–35.8 kWh). Up to six towers can be paralleled for 215 kWh total. The system operates up to 864 V with 1 C charge/discharge capability. The batteries are rated for over 8 000 cycles or 15 years and provide 24/7 app‑based monitoring.

Available sets (all with Solis 15 kW HV inverter)

Why this combination?

• Flexible PV connection: up to 16 A MPPT current and 1.6 DC/AC ratio with 160 % PV input capability, allowing more PV power than inverter rating.

• Fast battery response: charges/discharges up to 50 A/10 kW; modules support 1 C for full charge/discharge in one hour.

• Modular scalability: expand from two to seven modules; up to six towers in parallel.

• High reliability: LiFePO₄ chemistry with > 8 000 cycles or 15 years; integrated AFCI protection and UPS switchover < 10 ms ensure safe operation.

• Smart monitoring: SolisCloud for the inverter and Pylontech app for the battery provide real‑time oversight.
