Step 5 Hold down the black start button for 5s to activate the battery. The power control
module LED blinks three times and then the green indicator is steady on. The
battery comprehensive LED blinks three times and then the green indicator is
steady on. The ring LED blinks three circles.
Step 6 Log in to the FusionSolar app. Choose Maintenance > Battery maintenance >
Recharge, start battery recharge, and monitor the charge status of the lithium
battery in real time until the recharge is complete.
Step 7 Confirm that the recharge is complete if five indicators of the ring LED are on and
the comprehensive LED of the battery expansion modules is steady green.
Step 8 After the battery is charged, switch off the inverter input AC circuit breaker and
then the battery input circuit breaker. If other batteries need to be charged, repeat
the preceding steps.

8.5 Storage with Low SOC
After the ESS is powered off, static power consumption and self-discharge loss
may occur in battery modules. Therefore, charge battery modules in a timely
manner and do not store the ESS in low state of charge (SOC). Otherwise, the ESS
may be damaged due to overdischarge, and battery modules need to be replaced.
Storing the ESS with low SOC may occur in the following scenarios:
●
●
●
●
●
Regardless of scenarios, the ESS must be charged within the maximum interval
corresponding to the SOC when the ESS is powered off. If the ESS is not charged
beyond the maximum interval, it may be damaged due to overdischarge.
Power-Off SOC Before Storage
SOC ≥ 5%
0% ≤ SOC < 5%
Issue 11 (2023-04-15)
DC SWITCH on the power control module is OFF.
The ESS power cables or signal cables are not connected.
The ESS cannot be charged due to a system fault after discharge.
The ESS cannot be charged due to incorrect configurations in the system.
The ESS cannot be charged due to no PV input and long-term mains failure.
NO TE
When the SOC of the ESS decreases to 0%, charge the ESS within seven days. Any
permanent battery damage due to customer's failure to charge the ESS properly is not
covered under warranty.
