I recently connected my new Schneider Conext SW2024 and I'm having issues getting it to charge my BigBattery 24v Powerblock. I think that I have all the settings to the proper rates to charge the battery based on the battery specs on the website but I still get an error a few minutes into charging.
49 - DC Over Voltage: Cause: Voltage at the DC input terminals is above the High Battery Cut Out Setting. Solution: Clear the fault and attempt restart. Ensure battery voltage is 21-33 VDC (default settings) at Conext SW terminals. Check all other charging source outputs, and battery cables.
The charger shows the battery at 28.4v when it cuts out and I have the "High Battery Cut Out" set at 29.2v since that is the max on the battery specs.
