Fault & error codes — iStore IS-BATT

Extracted from the installation manual

6 documented

Showing 6 of 6. The official install manual is the authoritative source — always confirm before acting.

3000criticalCall your installer
Manual (PDF)
Low battery DC input bus voltage
Likely cause
1. The DC bus voltage of the battery is low. 2. The battery DC switch is OFF. 3. The battery cables are not correctly connected.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Check the cable connections to the Battery-1/2 power control module by referring to the quick installation guide. 3. After checking that the battery power cables are correctly connected, turn on the battery DC switch, AC output switch, and inverter DC input switch in sequence. 4. If the alarm persists, contact your dealer or Technical support.

Manual (PDF)
Abnormal battery power control module
Likely cause
A major fault has occurred on the internal circuit of the battery power control module.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Turn on the battery DC switch, inverter AC output switch, and DC input switch. 3. If the alarm persists on the Battery-1/2 power control module (the battery fault indicator is steady on), contact your dealer or Technical support.
3003criticalCall your installer
Manual (PDF)
Battery power control module fuse blown
Likely cause
The fuse of the battery power control module is blown.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch and wait for 5 minutes. 2. Replace the fuse of the Battery-1/2 power control module. 3. Turn on the battery DC switch, inverter AC output switch, and inverter DC input switch in sequence. If the alarm persists, contact your dealer or Technical support.

Manual (PDF)
Battery power control module reversely connected
Likely cause
The positive and negative terminals are reversely connected when the battery power control module connects to the inverter.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Check the cable connections to the Battery-1/2 power control module by referring to the quick installation guide. 3. After checking that the battery power cables are correctly connected, turn on the battery DC switch, AC output switch, and inverter DC input switch in sequence. 4. If the alarm persists, contact your dealer or Technical support.
3002warning
Manual (PDF)
Battery power control module overtemperature
Likely cause
1. The installation position of the battery power control module is not well ventilated. 2. The ambient temperature is excessively high. 3. The battery power control module is abnormal.
What to do
1. Check the ventilation and whether the ambient temperature of the Battery-1/2 power control module exceeds the upper threshold. 2. If the ventilation is poor or the ambient temperature is excessively high, improve the ventilation and heat dissipation. 3. If the ventilation and ambient temperature are normal, contact your dealer or Technical support.
3005warning
Manual (PDF)
Battery power control module DC switch OFF
Likely cause
1. The DC switch of the battery power control module is OFF. 2. The DC bus cable to the battery power control module is disconnected.
What to do
1. Turn off the inverter AC output switch, inverter DC input switch, and battery DC switch, and wait for 5 minutes. 2. Check the cable connections to the Battery-1/2 power control module by referring to the quick guide. 3.
