Why does my Phocos Any-Grid PSW-H-5kW-230/48V shut down and the buzzer is active?
Your Phocos Battery Charger might be shutting down with the buzzer active because the battery voltage is too low. The unit will attempt to re-charge the battery automatically during the start-up process. If that doesn't work, consider replacing the battery.
What to do if AC source exists but Phocos Any-Grid PSW-H-5kW-230/48V works in Off- Grid / battery mode?
If your Phocos Battery Charger is operating in Off-Grid/battery mode even when an AC source is available, it could be due to several reasons. First, check if the input circuit breaker has tripped and ensure the AC wiring is correctly connected. Another cause might be insufficient quality of AC power. In this case, verify that the AC wires aren't too thin or too long, and if you're using a generator, confirm it's working correctly and the input voltage range setting is appropriate. You might try switching from UPS mode to Appliances mode in the device operation settings. Also, check if “Solar / PV First” is set as the priority of the AC output source, if so, change output source priority to “AC input / utility first”.
What to do if my Phocos Any-Grid PSW-H-5kW-230/48V Battery Charger displays an overload error?
If your Phocos Battery Charger shows an overload error, try reducing the connected load by turning off some equipment.
What to do if EEPROM corrupted on Phocos Any-Grid PSW-H-5kW-230/48V?
Please contact your repair center and communicate the serial number of the affected unit.
What to do if AC output mode setting is different between Phocos units?
Switch off the units and check settings menu number 28. For parallel systems on a single phase, make sure each unit is set to “PAL” in settings menu number 28. For split-phase and 3-phase systems, make sure each unit has the same two first characters in settings menu number 28 (“2P” for split-phase “3P” for 3-phase) and is on the correct phase. If the problem remains, please contact your repair center.
What to do if detected AC input voltage and frequency differ between Phocos units?
Check the AC input wiring connection and restart the unit. Make sure the AC source starts up with the same voltage and frequency on each phase. If there are breakers installed between AC input and Any-Grid units, please be sure all breakers can be turned on the AC input at the same time. If the problem still remains, please contact your repair center.
What to do if detected battery voltage differs between Phocos units?
Make sure all inverters share same battery bank. Remove all loads and disconnect AC input and PV input. Then, check the battery voltage of all units. If the values from all inverters are close, please check if all battery cables are the same length and same material and cross-section. Verify the seat of each battery connection to the respective units. If the problem still remains, please contact your repair center.
What to do if firmware version of each Phocos inverter is not the same?
Check the version of each inverter firmware via the screen and make sure the versions are same. If not, contact your installer to provide a firmware update. After updating, if the problem still remains, please contact your repair center.
How to resolve AC output current unbalanced issue on Phocos Any-Grid PSW-H-5kW-230/48V?
To address an unbalanced AC output current on your Phocos Battery Charger: First, restart the inverter. Then, remove excessive loads and re-check load information from the LCD of the units. If the values are different between units on the same phase, check if the AC input and output cables are the same length, cross-section and material.
Why is the internal relay of Phocos Any-Grid PSW-H-5kW-230/48V switched on and off repeatedly when the unit is turned on?
If the internal relay of your Phocos Battery Charger switches on and off repeatedly when you turn it on, the battery might be disconnected. Check if the battery wires are securely connected.
