What is a single-phase hybrid inverter?

A single-phase hybrid integrates DC→AC conversion (230 V), MPPT for the panels, and battery management. With it, you can prioritize solar energy, store surplus, and have EPS/UPS output to maintain critical loads during grid outages.

Key advantages

• Savings and flexibility: self-consumption with or without export, battery use during expensive hours.
• Continuity: automatic backup (depending on model) for essential circuits.
• Monitoring: portal/app to view production, consumption, and SOC in real time.
• Scalability: expansion of PV strings and battery modules (LV/HV).

Battery compatibility

• LV 48 V: well-sized 48 V lithium or lead-acid banks (according to manufacturer).
• HV: chains of high voltage modules with BMS communication (CAN/RS485).

How to choose your single-phase hybrid

• Output power (kW) and start-up peaks (compressors, pumps).
• Number of MPPT and ranges (Voc/Vmp and current) according to string configuration.
• Battery system (LV 48 V or HV) and charge/discharge power (kW).
• Functions: EPS/UPS, zero export, programmable loads, limiter with meter/CT.
• Communications: RS485/CAN with BMS, Wi-Fi/LAN for monitoring.
• Installation: IP rating, ventilation, space, and DC/AC protections (SPD, fuses, disconnectors).

General specifications

Best practices

• Check Voc at minimum temperature and current per MPPT before closing strings.
• Use a certified/compatible battery by the hybrid manufacturer.
• Size usable kWh and charge/discharge power to your consumption habits.
• Install SPD, fuses, and disconnects in DC/AC; ensure proper grounding.
• Configure meter/CT and operating modes (self-consumption, back-up, zero export).

If your installation is 230 V and you want to combine self-consumption, storage, and backup, a single-phase hybrid inverter offers you the ideal balance between efficiency and safety. For 3-phase grids, see three-phase hybrids.
