- Vendor: Solis
Specifications
Product Description
The Solis S5-EH1P3K-L Hybrid Inverter Single-phase 3kW 48V is designed for homes seeking self-consumption with reliable and safe storage. With dual high-precision MPPT, automatic backup in less than 20 ms, and IP65 protection rating, this device maximizes solar energy and maintains critical loads during brief outages. It manages 48 V batteries (lithium-ion and lead-acid) via CAN communication and an intelligent EMS that optimizes charging/discharging to extend battery life and increase savings.
Main Features
- Nominal grid power: 3 kW single-phase (3.3 kVA max.).
- Backup (backup output): up to 3 kW with switching time <20 ms for critical loads.
- 2 MPPT / 2 strings with 15 A per input (admissible Isc 22.5 A) and MPPT range 90–520 V.
- Recommended PV generator: 6 kW; usable PV power up to 4.8 kW.
- 48 V battery: range 42–58 V; max. charge/discharge 3 kW (≈62.5 A); lithium/lead compatibility.
- Max. efficiency >97.1% (EU >96.5%); IP65 chassis and natural convection cooling.
Advantages or Benefits
- Service continuity with fast transfer (<20 ms) that maintains lighting, router, pumps, or sensitive electronics.
- Higher production thanks to 2 MPPT of 15 A that accept high-current TOPCon/HJT modules without throttling.
- Energy savings: EMS 24/7 prioritizes self-consumption, schedules night charging, and limits export if needed.
- Clean and silent installation (no fans), MC4 connectors, and quick-connect AC plug.
- Advanced safety: AFCI, SPD Type II on DC/AC, anti-islanding, and ground fault monitoring.
Purpose or Applications
Ideal for homes with medium daytime consumption and basic backup needs: remote work, refrigerator, lighting, electronics, and small motors. Its 3 kW power and 48 V battery allow coverage of daily peaks, stabilization of the internal grid, and taking advantage of time-of-use tariffs.
