Solis S5-EH1P(3-6)K-L (Smart) Single Phase Low Voltage Energy Storage Inverter
The Solis S5-EH1P(3-6)K-L is a
residential hybrid (energy storage) inverter designed to work with solar PV + battery systems. It provides both grid-tied PV conversion
and battery backup / storage functionality, enabling households to manage solar energy generation, storage, and backup power in one integrated device.
It’s part of the “low voltage, single-phase” inverter family — appropriate for typical home installations.
Key Features & Functionality
- Smart Energy Management: The inverter includes an intelligent Energy Management System (EMS) that can manage battery charging and discharging based on time-of-use tariffs, maximizing self-consumption and optimizing energy costs.
- Backup Power / Uninterruptible Supply: In case of grid power outage, the inverter can provide backup power (up to 5 kW) to support essential loads.
- Fast Switching: Backup switchover (from grid to battery) occurs in under 20 milliseconds, enabling seamless transition with minimal interruption.
- Battery Compatibility: The unit works with mainstream lithium-ion as well as lead-acid batteries — giving flexibility in battery choice for different markets or needs.
- Flexible & Scalable: Suitable for various PV & battery system sizes, which makes it adaptable depending on how many solar panels and battery capacity you plan.
- User Interface & Monitoring: It includes a 7-inch LCD screen for monitoring and configuration, plus support for remote monitoring/control (WiFi/GPRS or other communications) for real-time plant status.
- Safety & Protection: Equipped with multiple protection and fault-monitoring features (e.g. short-circuit protection, overcurrent, surge protection, ground-fault monitoring, etc.), plus AFCI (Arc-Fault Circuit Interruption) to reduce fire risk.
- Durable & Reliable: The inverter uses a “finless” design (natural cooling), enhancing lifespan and reducing maintenance.

Use Cases / Ideal Applications
- Residential homes with rooftop solar panels + battery storage — for self-consumption, backup power during outage, and energy cost optimization.
- Situations where you want grid-tied + battery backup + solar storage in one compact hybrid inverter.
- Users who prefer flexibility (can choose lithium or lead-acid batteries), and want remote monitoring + smart energy management (especially convenient if you have time-of-use tariffs).
- Areas with unstable grid or frequent outages — the inverter’s fast <20 ms switchover helps ensure essential loads (lights, fridge, communication, etc.) stay powered.
