Fault codes (22)output stops · red LED solid
The inverter is overloaded and cuts off its output; the red LED is solid on.
CauseThe connected load exceeds the rated output power of the inverter while running in battery mode.
Recommended fixTurn off the inverter, decrease the load to less than the rated output power of the inverter, then turn the inverter on again. If the overload happens while the AC input is on, wait 30 seconds and the fault will clear automatically.

The inverter output voltage is above the allowed range.
CauseThe inverter measured its own AC output voltage above the permitted range. Output voltage is regulated entirely inside the unit, so this points to an internal regulation or feedback fault rather than a wiring issue.
Recommended fixRestart the inverter. If the fault persists, contact the repair center.

A short circuit is detected on the inverter AC output.
CauseThe AC output wiring or a connected load is short-circuited.
Recommended fixIf the AC input is on, cut off the AC input first, then turn off the inverter, disconnect all AC output wiring and turn it on again. If the screen still displays the fault, contact the repair center. If the inverter can work again, check the output wiring and load and make sure none of them are short-circuited.

The battery voltage is above the allowed maximum.
CauseThe battery voltage is too high; on a 48V system a reading above 60V indicates a battery problem.
Recommended fixRead the battery voltage from the screen and measure the battery voltage with a multimeter. If both readings are more than 60V, the battery may have a problem and you must stop using it.

The internal temperature of the inverter is too high.
CauseThe inverter has overheated.
Recommended fixTurn off the inverter and let it cool down. After the temperature is back to normal you can use it again.

Over current is detected while charging the battery.
CauseWhile charging the battery, current through the charger stage exceeded its protection limit. The trip is raised by the internal charging circuit, so persistent recurrence indicates a charger-stage fault rather than a battery wiring problem.
Recommended fixContact the repair center.

The inverter soft start did not complete in time.
CauseAt power-up the soft-start ramp failed to bring the inverter stage to its working point within the allowed time — an internal power-stage or pre-charge fault.
Recommended fixContact the repair center.

The inverter output voltage is below the allowed range.
CauseA high-power load is dragging the output voltage down, or an internal fault has triggered.
Recommended fixTurn off the inverter, disconnect all AC output wiring and then turn it on. If it still shows the fault, contact the repair center. If it works normally, check whether the output is connected to a big power load; disconnect the big load, turn on the inverter and confirm it can work normally.

The battery is disconnected from the inverter.
CauseThe battery connector is loose or disconnected.
Recommended fixCheck the battery connector.

The internal current sensor reports an abnormal value.
CauseThe inverter's internal current sensor returned an out-of-range or implausible reading, so the control board can no longer trust its output-current measurement.
Recommended fixContact the repair center.

The output is heavily overloaded or short-circuited.
CauseA heavy overload or a short circuit is present on the AC output.
Recommended fixRefer to the handling for fault 13 (overload) and fault 15 (output short).

CAN communication data is lost between inverters in the parallel system.
CauseParallel communication cables between inverters are loose, damaged or not connected well.
Recommended fixCheck if the communication cables are connected well and restart the inverter. If the problem remains, contact your installer.

In the parallel system, the inverters measure different battery voltages.
CauseThe inverters do not share the same battery group, or the battery cables differ in length or material type.
Recommended fixMake sure all inverters share the same groups of batteries. Remove all loads and disconnect the AC input and PV input, then check the battery voltage of all inverters. If the values from all inverters are close, check that all battery cables are the same length and material type; otherwise, contact your installer to provide the SOP to calibrate the battery voltage of each inverter. If the problem still remains, contact your installer.

The inverters in the parallel system detect different AC input voltage or frequency.
CauseThe utility wiring differs between inverters, or the units do not receive utility power at the same time.
Recommended fixCheck the utility wiring connection and restart the inverter. Make sure the utility starts up at the same time; if there are breakers installed between the utility and the inverters, make sure all breakers can be turned on at the AC input at the same time. If the problem remains, contact your installer.

The AC output current differs too much between inverters in the parallel system.
CauseExcessive loads, or AC input and output cables of different length or material type between inverters.
Recommended fixRestart the inverter. Remove some excessive loads and re-check the load information from the LCD of the inverters. If the values are different, check that the AC input and output cables are the same length and material type. If the problem remains, contact your installer.

The AC output mode (LCD setting #28) is not set consistently across the parallel system.
CauseLCD program #28 is set to different output modes on the paralleled inverters.
Recommended fixSwitch off the inverter and check LCD setting #28. For a parallel system in single phase, make sure no 3P1, 3P2, 3P3, 2P1 or 2P2 is set on #28. For supporting three-phase systems, make sure no PAL, 2P1 or 2P2 is set on #28. For supporting split-phase systems, make sure no PAL, 3P1, 3P2 or 3P3 is set on #28. If the problem remains, contact your installer.

Power is feeding back into the inverter output.
CauseL and N cables are connected reversely, or sharing cables are wired between inverters on different phases.
Recommended fixRestart the inverter. Check if the L and N cables are not connected reversely in all inverters. For a parallel system in single phase, make sure the sharing cables are connected in all inverters; for three-phase or split-phase systems, make sure the sharing cables are connected in the inverters on the same phase and disconnected in the inverters on different phases. If the problem remains, contact your installer.

The inverters in the parallel system run different firmware versions.
CauseThe CPU firmware versions of the paralleled inverters differ.
Recommended fixUpdate all inverter firmware to the same version. Check the version of each inverter via the LCD setting and make sure the CPU versions are the same; if not, contact your installer to provide the firmware to update. After updating, if the problem still remains, contact your installer.

Warning codes (6)unit keeps running · red LED flashing
Overload warning; the code flashes on the LCD and the red LED flashes.
CauseThe connected load is above the inverter's rated output power.
Recommended fixReduce the connected load. The inverter forbids overload; the remaining working time depends on the percent of load.

The inverter derates its output power because the utility voltage is low.
CauseThe AC input voltage is low (about 90-170V).
Recommended fixRead the voltage from the screen and confirm the voltage of the AC input is about 90-170V. If it is, the AC input voltage is low and the unit can work normally. If not, contact the repair center.

Common questions about IVPS3524P1G1-LV error codes
- What is the difference between a fault and a warning on the IVPS3524P1G1-LV?
- A fault cuts the unit's output and the red LED stays solid — this page lists 22 of them for the IVPS3524P1G1-LV. A warning only flashes the red LED and the unit keeps running; there are 6 warning codes here. Resolve the cause of a fault before restarting; warnings can usually be cleared while the unit runs.
- Which model numbers does this page cover?
- The IVPS3524P1G1-LV shares its firmware and fault table with 5 other model numbers: IVPS5048P1G1-LV, IVPS7548P2G1, IVPS10048P2G1, IVPS3.5~10kVA-US, IVPS3-5-10KVA. If your unit is any of these, every code on this page applies to it.
- Where do these codes come from?
