The Solis S6-EH1P5K-L-PLUS 5kW Hybrid Solar Inverter is an advanced single-phase photovoltaic energy storage system designed for residential properties, medium-to-large homes, and commercial offices. It concurrently manages power from rooftop solar panel strings, a 48V battery bank, and the local utility grid.
In Bangladesh, where frequent load shedding, grid voltage variations, and rising tiered electricity tariffs disrupt daily operations, this hybrid inverter operates as an intelligent energy hub. It prioritizes direct solar self-consumption, stores midday surplus energy into battery banks, supports grid feed-in under net-metering schemes, and delivers uninterrupted backup electricity during blackouts.
5kW Rated Continuous Power: Delivers continuous 5000W output for both standard on-grid feeding and essential backup circuits.
Sub-4ms UPS Switching: Automatically transitions to emergency battery backup in under 4 milliseconds during grid failures, ensuring uninterrupted power for servers, computers, and medical devices.
High-Current 112A Battery Management: Supports rapid charging and discharging with programmable 6-stage charge profiles to maximize battery service life.
Heavy-Duty Solar Sizing: Accommodates up to 10kW recommended PV arrays (8kW max usable DC input) across two independent MPPT trackers.
IP66 Enclosure & Natural Cooling: Fully sealed against dust and torrential rainfall, utilizing a fanless heat sink for completely silent operation.
Parallel Expansion & Net Metering: Net-metering ready, with support for networking multiple units to form single-phase or three-phase systems up to 48kW, plus AC coupling for existing solar installations.
Dual MPPT Tracking (16A / 16A Input): Dual tracking channels with an operating window of 90V–435V optimize solar energy harvest from roofs with split orientations or partial shading.
2× Rated Peak Apparent Power: Delivers double rated output power for 10 seconds during backup mode to easily handle starting surge currents from refrigerators, water pumps, and air conditioner compressors.
Clean Power Quality: Produces clean pure sine-wave electricity with total harmonic distortion (THDi < 2%, THDv < 2%) and an adjustable power factor (0.8 leading to 0.8 lagging).
Smart Low-Voltage Battery Safety: Designed for safe 40V–60V DC battery architectures with standard CAN and RS485 communication protocols for intelligent Lithium BMS integration.
