The Must 3.2kW inverter and Beesman 2.7kWh battery can be connected physically, but manual configuration is required for optimal performance and safe operation. These devices do not support automatic communication via CAN or RS485.
Key Must Inverter Specifications:
- Model: Must PV18-3224 VPM II
- System Voltage: 24V DC
- Rated Power: 3.2kW / 3200W
- Maximum Charge Current: 120A (AC + Solar combined)
Beesman Battery Specifications:
- Nominal Voltage: 25.6V (LiFePO₄)
- Capacity: 2.7kWh
- Recommended Charge Voltage: 28.4V (Bulk/Absorb)
- Float Voltage: 27V
- Discharge Cutoff: 21–22V
Follow these steps to configure your Must inverter for use with the Beesman battery:
- On the inverter’s LCD, navigate to Setting Mode → Battery Type → select “USER” or “Li”.
- Set Bulk/Absorb Voltage to 28.4V.
- Set Float Voltage to 27V.
- Adjust Low DC Cutoff to 21–22V to protect against deep discharge.
- Limit Max Charge Current to the Beesman’s recommended level (typically 50–60A).
- Save and reboot the inverter to apply new settings.
Tip: Use correctly sized cables (minimum 25mm² for short runs) to prevent voltage drop and overheating.
While the Beesman 2.7kWh battery works with the Must inverter, its capacity may be modest for extended usage. You can:
- Expand capacity by connecting additional Beesman batteries in parallel (same voltage and state of charge).
- Manage loads by keeping continuous usage below 80% of the inverter’s capacity (≈2560W).
- Monitor performance via the inverter’s LCD display for daily and total energy production.
This configuration ensures both safety and durability — ideal for homes and small businesses seeking energy independence.
Note: These units do not auto-sync or exchange data. Manual configuration is required for optimal results. The Beesman’s integrated BMS safeguards your system by preventing overcharge, short-circuit, and over-discharge conditions.
⚡ Black Friday Offer: Available only during the promotion week — includes free professional installation within Harare and discounted hardware rates nationwide.
Reserve your system early through Sona Solar Zimbabwe to secure your slot before the festive installation rush.

Frequently Asked Questions
Must 3.2kW Inverter & Beesman 2.7kWh Battery
No, automatic communication between these two brands is unlikely. The Must inverter’s closed-loop BMS compatibility typically supports select manufacturers only. You must use manual configuration for this setup.
Access the inverter’s LCD menu and manually enter the correct battery parameters from the Beesman datasheet:
- Battery Type: Set to "USER" or "Li" (not AGM or FLd).
- Bulk/Absorb Voltage: Charging voltage for the main charge cycle.
- Float Voltage: Voltage for maintaining a full charge.
- Max Charge Current: Limit this to the Beesman battery’s safe maximum, not the inverter’s default (which can be 120A).
- Low DC Cut-off Voltage: Set the minimum discharge voltage to protect the battery.
The Beesman 2.7kWh battery can power the inverter but will discharge quickly under heavy load. Running the inverter at full capacity (3.2kW) would deplete the battery in under an hour. It’s best suited for moderate loads or to be paired with additional batteries.
Keep your continuous power draw below 80% of the inverter’s rated output — about 2,560W. This helps avoid overheating, ensures stable performance, and extends inverter lifespan.
Yes, you can connect multiple Beesman batteries in parallel to increase total capacity, as long as all units share the same voltage (24V). Make sure they have similar charge levels before connecting.
- Configuration: Ensure “User” battery mode is selected and voltage parameters match the Beesman specs.
- Cabling: Confirm correct polarity and secure connections.
- Over-voltage lockout: The inverter might block charging if it detects high voltage — perform a reset if needed.
- Breakers: Check both inverter and external DC breakers for tripping.
This usually indicates voltage drop or a premature BMS cutoff:
- Cable Gauge: Thin cables can cause voltage drop under load — use correctly sized wires.
- BMS Cutoff: The battery’s BMS may be shutting down to protect the cells, which cuts power abruptly and triggers a low-voltage alarm.
Since Must and Beesman are unlikely to communicate directly via CAN or RS485, ignore communication errors. To fix issues:
- Ensure inverter communication mode isn’t set to “BMS”.
- Disconnect any communication cable causing false errors.
- Recheck all manual configuration settings.
- If errors persist, contact your supplier for firmware updates or diagnostic support.
