Solis 3kW Single Phase Hybrid Solar Inverter (S6-EH1P3K-L-PLUS)

Description

Product Overview

The Solis S6-EH1P3K-L-PLUS 3kW single-phase hybrid solar inverter delivers flexible energy independence by seamlessly managing inputs from solar PV arrays, energy storage batteries, and the utility grid. Operating with a maximum PV input power of 4,500W and a maximum DC input voltage of 600V, it efficiently converts solar energy for immediate household consumption, charges 48V nominal battery banks, and exports surplus electricity where permitted. Its compact, wall-mounted form factor and silent, fanless operation make it well-suited for indoor and outdoor installations across Bangladesh.

Main Features

This inverter features an integrated 3,000W backup output that shifts to battery power in less than 20 milliseconds during grid failures, ensuring uninterrupted operation for sensitive electronics. It supports both modern Lithium-ion and conventional Lead-acid batteries within a 40V to 60V operating window, delivering up to 60A charge and discharge current. System tracking is managed via an on-unit LCD and can be paired with optional Wi-Fi or GPRS modules for remote monitoring and firmware updates via the SolisCloud platform.

Benefits

• Uninterrupted Power: Acts as an automatic high-speed UPS during frequent grid load-shedding, protecting critical loads like computers, lighting, and refrigeration.

• Optimized Energy Cost: Enables self-consumption maximization, peak shaving, and time-of-use (TOU) battery charging during off-peak hours to reduce monthly electricity expenditures.

• System Flexibility: Operates efficiently in on-grid, off-grid backup, and self-consumption configurations without requiring complex external switchgear.

• Low Maintenance & Long Life: Natural convection cooling eliminates moving parts, reducing dust build-up, mechanical wear, and operational noise.

Applications

Designed primarily for urban and suburban residential homes, retail shops, light commercial workspaces, and remote premises requiring a dependable 230V AC single-phase supply with battery storage integration.

7. FAQ

Q: Can the Solis S6-EH1P3K-L-PLUS keep appliances running during load shedding?

A: Yes. The inverter features an integrated backup circuit with an automatic switchover time of under 20 milliseconds, which supplies stored battery and solar power to connected critical appliances during a grid outage.

Q: What battery types are compatible with this inverter?

A: It is compatible with both 48V nominal Lithium-ion (LiFePO4) and Lead-acid (tubular/gel/deep-cycle) batteries within a voltage window of 40V to 60V.

Q: Can this inverter operate if the utility grid goes down?

A: Yes. In backup mode, the inverter forms an independent 230V AC single-phase micro-grid from your solar panels and connected battery bank to supply your dedicated backup loads.

Q: Does this model require an active cooling fan?

A: No. It uses natural convection cooling with a rear heat sink, allowing it to operate silently (under 30 dBA) while preventing dust from being drawn inside the housing.

Q: Can I monitor energy production from my smartphone?

A: Yes. By adding an optional Solis Wi-Fi or GPRS datalogger stick, you can track real-time power generation, battery status, and consumption through the SolisCloud mobile app or web browser.

Q: What is the maximum solar panel wattage I can connect to this inverter?

A: The inverter supports a maximum DC input power of up to 4500W, provided the total open-circuit voltage stays below 600V and within the MPPT operating range of 90V to 520V.
