Switch off the power supply before installing batteries. Note the positive and negative polarities when installing batteries. Do not short-circuit
the positive and negative poles of the same battery or battery string. Otherwise, a great amount of energy is released, causing personal injury and damage to equipment. When installing a battery string, retain at least one breakpoint to prevent a loop being formed. After checking that the installation is correct, close the breakpoints to finish the installation. Before powering on a battery string, ensure that all bolts connecting batteries are tightened to the required torque. Do not use unsealed lead-acid batteries. Place and secure lead-acid batteries horizontally to prevent device inflammation or corrosion due to flammable gas emitted from batteries. During the installation, insulate the terminals of cables connecting batteries. Ensure that the terminals do not come into contact with metal components such as the cabinet. When handling a battery, ensure that its electrodes are upward. Do not tilt or overturn batteries.
1.6.3 Protection Against Battery Short Circuits

Issue 05 (2019-10-25)

PowerCube 500 (ICC30) User Manual

1 Safety Precautions

Battery short circuits can generate high instantaneous current and release a great amount of energy, which may cause equipment damage or personal injury.
If permitted, disconnect the batteries in use before performing any other operations.
1.6.4 Protection Against Flammable Gas

Do not use unsealed lead-acid batteries. Place and secure lead-acid batteries horizontally and ensure that hydrogen discharge
measures are normal to prevent inflammation or device corrosion due to flammable gas emitted from batteries.
Lead-acid batteries emit flammable gas if they work abnormally. Store lead-acid batteries in a place with good ventilation, and take fire safety precautions.
1.6.5 Battery Leakage Handling Regulations

High battery temperature may result in battery distortion, damage, and electrolyte overflow.
If the battery temperature is higher than 60°C, check the battery for electrolyte overflow. If the electrolyte overflows, handle the leakage immediately.

When the electrolyte overflows, absorb and neutralize the electrolyte immediately.
When moving or handling a battery whose electrolyte leaks, note that the leaking electrolyte may hurt human bodies. Neutralize and absorb the electrolyte with sodium bicarbonate (NaHCO3) or sodium carbonate (Na2CO3) before moving the batteries.
1.6.6 Lithium Battery Scenarios
The precautions for lithium battery operations are similar to the precautions for lead-acid battery operations except that you also need to note the precautions described in this section.

There is a risk of explosion if a battery is replaced with an incorrect model.
A battery can be replaced only with a battery of the same or similar model recommended by the supplier.

Issue 05 (2019-10-25)

PowerCube 500 (ICC30) User Manual

1 Safety Precautions

When handling lithium batteries, do not place them upside down, tilt them, or bump them against the ground.
Keep the battery loop disconnected during installation and maintenance.
When the ambient temperature is lower than the lower limit of the operating temperature, do not charge the battery (0°C Charging is not allowed). Otherwise, a short circuit occurs inside the battery.
Do not throw a lithium battery in fire.
When maintenance is complete, return the waste lithium battery to the maintenance office.

1.7 PV Module Safety
Before installing, operating, and maintaining photovoltaic (PV) modules, read the instructions provided by the PV module vendor. The safety precautions specified in this document are highly important precautions that require special attention. For additional safety precautions, see the instructions provided by the PV module vendor.

Before installation and maintenance, put on a safety helmet, goggles, insulation gloves, and protective clothing to avoid personal injury.
Before installing and maintaining PV modules, cover all PV modules totally using opaque materials to avoid electric shocks caused by generated currents.
Never focus sunlight on PV modules using a mirror or lens, because this may damage PV modules and cause personal injury.
When moving PV modules, do not hold connection boxes or power cables, because they are not designed to support the weight of PV modules.
Exercise caution when moving PV modules to avoid collision. Improper movement and placement may cause the glass plates on PV modules to break and lose electrical performance, which renders the PV modules useless.
In strong wind, do not install PV modules at heights.
To install or maintain a high support, you must set up a support platform and use a safety helmet or safety belt.
Do not drill holes in, step on, or place heavy objects on PV modules, because these actions may damage PV modules.
At least two persons are required to move and install PV modules. Only the aluminum frame of the PV modules can be raised. Exerting force on the front or rear surface of the PV modules using your head is prohibited. This may cause hidden cracks in the PV modules.

Measure
In the first year, collect real-time data when discharging is about to complete at least once every six months.
From the second year, check the battery capacity every three months. If a historical alarm indicates that an electrochemical cell is frequently overcharged or overdischarged, the voltage of the electrochemical cell is always near the charge or discharge protection threshold. This causes insufficient backup time. Therefore you need to replace the ESM as soon as possible.

Note: The SOC indicator indicates that charging or discharging is about to complete. For details, see the SOC indicator description.

Symptom Possible Cause

Solution

No output

The cables to PV modules are not connected properly.
PV modules are faulty.

Check whether the cables are loose, disconnected, or broken. If yes, reconnect the cables properly or replace them.
Use a multimeter to check whether each PV input has an output voltage, and use a clamp meter to check whether each PV input has a current. If no voltage or current is detected, check the PV modules.
Use a multimeter to check whether each PV module has an output voltage. If a PV module has no output voltage, replace it.
On a sunny day, check the output voltage of each PV module. The voltage of 150 W PV modules should range from 20 V DC to 25 V DC, while that of 200 W PV modules should range from 40 V DC to 45 V DC. If the output voltage of a PV module is not within the range, replace it.

The battery terminal or cable is dirty, which increases the connection voltage drop.

Measures Clear the dirt and reinstall the bolts.

In the initial operation period of a battery string, the battery string can discharge properly but the power supply to the load is disconnected quickly.

The BLVD voltage is greater than the maximum value in the power system.

Adjust the BLVD voltage to a normal range based on site requirements.

For a 2 V battery, the measured battery string voltage is about 4 V lower than the rated value.
For a 12 V battery, the measured battery string voltage is about 24 V lower than the rated value.

One battery is connected reversely.

Connect the battery correctly based on the polarity marks of battery terminals or the plus and minus signs on the battery cover.

In the initial operation period of a battery string, batteries have different voltages.

Batteries have a slight difference in the internal structure or in the storage and transportation conditions from each other.

After batteries are charged in float mode for three months, the voltages of all batteries become the same.
