Quantity
The MR-SPF6.5K-LP1-TL20E is a 6.5kVA / 6.5kW single-phase hybrid solar inverter built to keep your home or shop powered through load shedding. It uses solar power first and the utility grid as support, so your appliances keep running while you cut down on grid and generator use.
If you are looking for an MR solar inverter that handles a wide PV voltage range (60V to 450V MPPT), delivers a pure sine wave output and can even run without a battery, this model covers all three. It supports lead-acid, lithium and user-defined batteries on a 48V system.
Its compact, high-frequency design weighs only 10 kg, which makes wall mounting and installation easier than with bulky traditional units.
Key Features
6.5kW rated power with power factor 1: Delivers the full rated wattage as usable power, so you can run more of your real load, such as AC, pump, fridge and lights.
Wide MPPT range of 60V to 450V (500Voc max): Works with many solar panel string configurations and keeps harvesting energy in changing light.
Pure sine wave AC output: Provides clean power that is safer for sensitive electronics such as TVs, computers and motors.
Solar and utility grid can power loads at the same time: Reduces your electricity draw during the day and keeps loads stable when sunlight drops.
Dual AC output: Lets you separate loads on two outputs for more flexible wiring and load management.
Works without a battery: The inverter can still operate from solar and grid when no battery is connected (minimum 80VDC PV input in this mode).
Feed-in to grid function: Allows surplus solar energy to be fed back to the grid where local rules permit.
CAN / RS485 BMS communication: Connects to compatible lithium batteries for safer, smarter charging.
Built-in WiFi module: Lets you monitor system status remotely from your phone.
High-frequency, lightweight design (336 x 410 x 110 mm, 10 kg): Saves space and simplifies installation.
Why Choose This 6.5kW Hybrid Solar Inverter
This hybrid solar inverter suits users who want reliable backup and lower energy bills without a complicated setup. The 6.5kW output with a surge capacity of 2x rated power helps the system start motor loads such as pumps and compressors.
The 120A maximum charging current and up to 9000W PV input help recharge your battery bank quickly when sunlight is available. A quick transfer time of 10ms in UPS/APP mode helps keep sensitive devices running during power cuts.
For buyers comparing options, this MR solar inverter combines MPPT charging, grid support, BMS communication and WiFi monitoring in one compact unit. That makes it a practical choice for homes, shops and small offices in Bangladesh.
