Matching inverter to battery
All you have to do is convert from Watts In to Current in. To do that you use Watts Law: P=I*V. (Power=Current*Voltage) A LiFePo 4 12V nominal battery runs at arrond 12.8V but you have to plan on when the battery is nearly empty and running at near 12V, so the first estimate is 2000=I * 12.V or I = 2000W/12.V=166.7A

6 FAQs about [Battery and system do not match]
What happens if you skip the new battery-ECU matching?
By skipping the new battery-ECU matching, the ECU does not recognize the battery as new and continues to drive the charging cycle as though it was the old battery. This decreases fuel economy and significantly shortens the service life of the new and unmatched battery.
Can a battery and an inverter communicate?
When installing a battery system it is important that the battery and the inverter are able to communicate via the battery BMS (battery management system). If the BMS and the inverter are not communicating a number of problems may arise.
Why do battery management systems take a long time?
If the cells are very different in State of Charge (SoC) when assembled the Battery Management System (BMS) will have to gross balance the cells on the first charge. This can take a long time as the maintenance balancing currents are generally very small compared to the Ah ratings of the cells (1 to 3mA/Ah).
What happens if BMS and inverter are not communicating?
If the BMS and the inverter are not communicating a number of problems may arise. This can lead to the batteries not obeying the battery settings on the inverter and can cause the batteries to become unbalanced or over discharged.
How often should batteries be charged for BMS communications?
For accurate BMS communications on multi-battery systems the batteries must be charged to 100% ideally once every 7-10 days. Was this article helpful? This article details how to establish and troubleshoot BMS communications with all compatible batteries.
When should a battery pack be balanced?
Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. If the cells are very different in State of Charge (SoC) when assembled the Battery Management System (BMS) will have to gross balance the cells on the first charge.
