+ | |||
+ | ==== The maximum charge and discharge current is limited to 25A, but the data sheet tells me the maximum is 100A. ==== | ||
The maximum current is limited to keep the battery healthy and reach the 10 year guarantee. In off-grid, the inverter can draw more than the 25A limit to run the loads, make sure you have sufficient batteries installed to keep the load per battery around this limit. | The maximum current is limited to keep the battery healthy and reach the 10 year guarantee.

- | **After charging the battery the charge current often changes between 0A and 25A.** | + | ==== After charging the battery the charge current often changes between 0A and 25A. ==== |
This is caused by cell balancing inside the battery. This happens with new batteries and after a deep discharge. | This is caused by cell balancing inside the battery. This happens with new batteries and after a deep discharge. | ||
+ | ==== My system isn't charging at the rated capacity, or my PV is shutting down ==== | ||
+ | Pylontech' | ||
+ | You can confirm if this is affecting your installation be entering the Pylontech Battery menu on your GX device, and then the Parameters Menu. This will report the Charge Current Limit (CCL) and Discharge Current Limit (DCL). | ||
+ | |||
+ | ==== My system only charges the battery to 52V ==== | ||
+ | When DVCC is enabled, the battery (via the CAN-bms) is responsible for the charge voltage. The Pylontech battery requests a charge voltage of 53.2V. We have however found that in practice this is too high. | ||
+ | |||
+ | The Pylontech battery has 15 cells in series, so 53.2V equates to 3.55V per cell. This is very highly charged and makes the system prone to go overvoltage. | ||
+ | |||
+ | It should also be noted that a LiFePO4 cell stores very little additional energy above 3.45V. | ||
+ | |||
+ | For this reason we opted to override the BMS and cap the voltage at 52V. This sacrifices almost none of the capacity and greatly improves the stability of the system. | ||
+ | |||
+ | ==== The battery won't charge to 100% ==== | ||
+ | Also see the question above. The state of charge of the battery is estimated based on the overall voltage and on how well balanced the internal cells are. Because we cap the battery voltage at 52V, the state of charge will sometimes rise very slowly once it reaches the mid-90s. This is normal and usually resolves over time. | ||
