MUST Hybrid Solar Inverters & ESS (PH11 Series)

MUST Energy is a smart energy technology company with over 20 years of experience and about 1,500 employees, listing an address in Foshan, China. It makes inverters, solar charge controllers, batteries, UPS systems, portable power stations and energy storage systems.

At Solar & Storage Live Philippines 2026 it showed the PH11 Series hybrid inverters: a single-phase low-voltage model for homes and a three-phase high-voltage model for C&I with peak efficiency above 97.5%. They pair with the LP Series LiFePO4 battery (up to 15 units in parallel, IP66). The company says it will keep focusing on Southeast Asia.

• PH11 single-phase hybrid inverter: low-voltage model for homes, IP66, grid-tied, off-grid or hybrid.
• PH11 three-phase hybrid inverter: high-voltage model with peak efficiency above 97.5% and multiple MPPT inputs.
• LP Series battery: LiFePO4, up to 15 units in parallel, IP66.
• Commercial energy storage: C&I storage systems in the product range.
• Portable power stations and all-in-one ESS: additional storage formats.
• Off-grid inverters and MPPT charge controllers: wider solar product range.

Home solar-plus-battery packages for households in Vietnam with frequent outages. Small commercial sites using three-phase hybrid inverters for peak shaving. Off-grid power for remote farms and island locations.

Hybrid inverters run grid-tied, off-grid or hybrid, suiting areas with unreliable grids. IP66 ratings on inverter and battery suit outdoor and humid sites. Batteries scale to 15 units in parallel. Company states a focus on local service support in Southeast Asia.

Southeast Asian markets with limited grid coverage and unreliable power are driving demand for distributed storage and off-grid systems, according to the company. Vietnam faces rooftop solar growth alongside peak-hour tariffs that favor hybrid systems.

Listed address: Foshan, China; about 1,500 employees and monthly capacity above 80,000 units. Exhibited at Solar & Storage Live Philippines on 19 May 2026 and listed for the 140th Canton Fair in October 2026.
