Check the DC voltage from the solar panels to ensure it''s within the inverter''s specified range. Reset the inverter by powering it off and on. If the error persists, test
Error E01 (battery over-discharged). My inverter''s cut off is 50v, with a reboot at 51v. I had assumed 50v meant ~14% remaining. Could both of these things be caused by

Error code E01 on the inverter typically indicates a fault in the inverter''s internal circuitry or a communication error. Start by checking all inverter connections for tightness and corrosion.
Inverter is supplied directly from the battery, and Battery Protect only switches off the remote pin of Orion. All 24V cables are 25mm2, waaay over necessary. When BP is to
Knowing the inverter fault code helps users stay calm when facing situations where a fault may occur and then deal with it appropriately, avoiding inverter failure. This article discusses the inverter fault code, how to read it, and
Addressing the ''E01'' error generally requires checking battery connections, ensuring appropriate voltage, and possibly troubleshooting the solar controller settings.
Check the DC voltage from the solar panels to ensure it''s within the inverter''s specified range. Reset the inverter by powering it off and on. If the error persists, test the communication cable
If so, E01 means the battery was over-discharged and E02 seems to mean the opposite. Confusing, but these systems absolutely require the battery to be in good health -
The more likely scenario for the E01 error appearing is when the controller has inadvertently been calibrated for 24V. The ARC-30 is a 12V/24V controller and like most multi voltage controllers,
Knowing the inverter fault code helps users stay calm when facing situations where a fault may occur and then deal with it appropriately, avoiding inverter failure. This article discusses the

During the inverter application process, the possibility of the inverter monitor displaying the inverter fault code is inevitable. Knowing the inverter fault code helps users stay calm when facing situations where a fault may occur and then deal with it appropriately, avoiding inverter failure.
Inverter error codes are often the first clue that something is wrong with your solar, backup, or industrial power system. These codes serve as the inverter’s way of “talking” to you, warning you of system errors, irregularities, or malfunctions that need attention. The sounding of the inverter alarm accompanies their appearance.
This method starts by turning off the DC input from the solar panels or battery and then the AC output. Wait 2-5 minutes, then turn the DC input back on and the AC output. For the smart inverter, you can first log in to the inverter’s monitoring app. Choose the menu that provides “Clear Fault” or “Reset System.”
The E01 error code appears when the controller is sensing an over-discharged battery bank. This can happen for one of two reasons. The first is very straightforward. The battery bank is actually over-discharged. If the battery voltage (12V system) is below 11.1V it will trigger the E01 code.
Most modern inverters, such as those from Joeyoung, feature a digital display or LCD screen and can be monitored via a mobile app. When a fault occurs, the display on the inverter will show a numerical or alphanumeric code. In power inverters, faults are also signaled by the alarm ringing on the inverter.
Hardware replacement, such as an inverter capacitor, MOSFET inverter, or inverter IGBT, is needed. There is a noticable drop in performance. Resetting inverter fault codes is not just about removing the error; it’s about solving the problem behind it.
