If your Freedom Won Camera Accessories inverter has shut down, it's likely because the battery's State of Charge (SoC) is below 10%. The inverter is designed to shut down under these conditions. To restore the system, you'll need to recharge the battery to above 15% using grid power, generator power, or solar power.
Why won't my Freedom Won Camera Accessories battery charge at more than 20A?
Your Freedom Won Camera Accessories battery might not be charging at more than 20A because the eTower has an automatic charge limit feature. If the charge current exceeds 85A for too long, the maximum charge current is reduced to 20A by the internal MOSFET controller. This condition will be cancelled once the charge current has reduced to zero, typically when the battery is fully charged.
What to do if Freedom Won Camera Accessories battery displays an alarm when switched on and will not connect?
If your Freedom Won Camera Accessories battery displays an alarm and won't connect when switched on, it's likely due to one of two reasons: 1. **State of Charge Mismatch:** The battery may be connected to other modules with significantly different State of Charge. The battery is running into overcurrent during charge or discharge. To solve this, switch off all other modules and charge or discharge the problem module until its voltage is within one volt of the others. Then, switch the other modules back on. 2. **Inrush Current:** It could be caused by inrush current to the inverter. Pre-charge the DC bus before switching on the battery.
Why does the Freedom Won eTower battery alarm come on and disconnect at 100% SoC?
If the Freedom Won Camera Accessories battery alarm activates and disconnects when it reaches 100% State of Charge (SoC), it's possible that one of the cells is reaching its maximum voltage value. Try reducing the charge voltage setting on the inverter to 55.5V and reset the battery by pressing the reset button for 6 seconds.
What does it mean if the alarm light comes on at low SoC on Freedom Won eTower?
If the alarm light comes on at a low State of Charge (SoC) on your Freedom Won Camera Accessories, it likely indicates the low SoC alarm is triggered below 10% SoC. To resolve this, increase the minimum pack voltage to 49V, or charge the battery above 10% SoC.

Offers solutions for common issues encountered with the eTower.
The Freedom Won eTower is a modular lithium iron phosphate (LiFePO4) energy storage system designed for small residential and light commercial applications. It offers a scalable solution, allowing for initial installations of 5kWh that can be expanded in 5kWh increments up to 20kWh. The system is manufactured by Freedom Won (Pty) Ltd in South Africa.
The eTower modules are designed to store energy and provide it to compatible inverters and system controllers. They feature an integrated Battery Management System (BMS) that monitors and controls various parameters to ensure safe and efficient operation. The BMS can communicate with external devices via CAN Bus or RS485 interfaces, allowing for intelligent control of charging and discharging processes. The system is primarily designed for easy stacking into a tower configuration using included plastic pedestals, but it can also be rack-mounted or wall-mounted.
