5. BUILDING A BATTERY BANK 5-1. Before building a battery pack Only create battery banks with batteries of the same type and capacity. Batteries have the same product code and software version. Do not mix with other models. ... -
Page 21: Parallel
5-3. Parallel Note: For RVC connection, an external 12v is required Note: Can be connected in paralleled up to 8. 6. Storage and care The storage temperature is -20°C to 60°C. The performance of the battery pack is affected by temperature. The most intuitive performance is the change in the battery pack capacity, which is normal. -
Page 22: Troubleshooting
7. Troubleshooting After the battery pack is fully charged, the voltage is too low or zero. Common error Solution If the battery pack is stored for a Please test the battery pack voltage. If the battery long time and not used, and it is not pack voltage value is less than 8V, it cannot be maintained following the regulations recharged and placed in isolation. - Page 23 battery pack are damaged. If there is damage, replace it. Then use the smell method to determine the smell of the battery pack. If there is an irritating electrolyte smell, it means that the battery pack has leaked. It is necessary to conduct a voltage test on each string of the battery pack.

If the battery's voltage drops below 10V and it Under voltage cannot be revived using the SC inverter/charger's LFP rescue mode, charge the battery with a low current (1A). Once the battery reaches 12V, you can switch the charger back to its normal current setting. - Page 25 Lithium batteries at the end of their life should be recycled and disposed of following local laws.
