Baery maintenance

Do dust cleaning and baery performance checks every month to ensure the operability of the product.

Scrapped products should be recycled immediately by the speciﬁed qualiﬁed vendor instead of being discarded at will and

risking safety hazards or severe environmental contaminaon.

Baeries in long-term storage should be charged to 50% - 60% SoC every 6 months.

If the M Baery displays any warnings or faults, users can perform troubleshoong based on the states of indicator lamps and

the buzzer.

Maintenance of inverters

1.1 Regular Maintenance

1 Troubleshoong and Maintenance

Inspect inverters every 6 months to ensure that the radiator of the inverters is not covered by anything. If it is,

stop the inverter and clean its radiator.

Inspect inverters every 6 or 12 months for any signs of damage in cables, ﬁxings, terminals, and the general

inverter device.

Inspect inverters every 6 months for anomalies in operaon, heat, or noise parameters.

Note：

The buzzer is designed to be enabled or disabled through the primary computer. It is disabled by default on shipment.

In case of a fault, the buzzer will sound for 0.25s in every 1s. In case of a protecon noce, it buzzes for 0.25s in every

2s (excluding overvoltage protecon). In case of an alarm, it buzzes for 0.25s in every 3s (excluding overvoltage

protecon).

Notes on reset buon (RST): When BMS is in sleep mode, press and hold the buon for 3 - 6s, the guard is then

acvated and the LED indicator lamps will light up for 0.5s in sequence from “RUN”. When BMS is acve, press and hold

the buon for 3 - 6s, the guard will then sleep and the LED indicator lamps will light up for 0.5s in sequence from Min.

SoC. When BMS is in sleep mode, press and hold the buon for 6 - 10s, the guard is then reset and all the LED

indicator lamps will light up simultaneously for 1.5s.

Upon reseng, the BMS sll reserves the parameters and funcons set by the primary computer. If you wish to restore

the original parameters, you can do it through the “Restore defaults” opon on the primary computer. However, the

operaon records and stored data (e.g. SoC, cycles, protecon records, etc.) will remain unchanged.

Common faults and corresponding soluons are as follows:

If the M Hybrid Inverter displays any warnings or faults, users can perform troubleshoong based on the state

of the LEDs and the alarm/fault info on the Smart Screen.

If the dot on the le of a fault entry is red, it means

this fault is current. If the dot is gray, it means that

this fault doesn’t exist anymore.
