Marsriva MR-SPF3.6K-LP1-TL20E 3.6kW Hybrid Solar Inverter

Find the Marsriva 3.6kW hybrid solar inverter price in BD here. The MR-SPF3.6K-LP1-TL20E is the bigger sibling of Marsriva's 2kW model, sized for larger homes, offices and shops that want to run more of their daily load on solar.

3.6kW of clean power

With a power factor of 1, the full 3.6kW is usable. Output is a pure sine wave at 208–240V ±5%, and surge capacity reaches twice the rated power, which helps when starting refrigerators, water pumps or an inverter AC compressor within the rating.

Up to 5000W of solar panels

• MPPT range 40–450V with a maximum open-circuit voltage of 500V
• Maximum PV input 5000W at up to 18A
• Solar charging current up to 100A

That is room for eight 600W-class panels in a well-designed array, enough to run daytime loads and charge the battery at the same time.

Solar and grid together

Solar and utility power can supply the load at the same time, so the inverter uses free solar first and only draws what it needs from the grid. It can also run without a battery during the day. When the grid fails, it switches in about 10 ms in UPS or appliance mode, or 20 ms in generator mode.

Battery flexibility and monitoring

Choose lead-acid, lithium or a custom profile. Lithium batteries can connect via RS485 or CAN for BMS communication. A dry contact is available for generator start, and the Wi-Fi module lets you check performance on your phone.

Installation

The inverter is IP20, for indoor wall mounting in a dry, ventilated room. It measures 284 x 420 x 104 mm and weighs 6.4 kg. Use a qualified installer for PV string design, DC protection and earthing.
