Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.

Ron was brilliant. He really tried to help. He spent hours trying to fix our GivEnergy AIO and ultimately it became apparent that it needed parts to fix the BMS management system. As there appears to be no replacement parts available on the market, he gave excellent advice on what options are now available to move forward. He is incredibly helpful and knowledgeable.
Called back within a day and gave good advice.
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.

Safety: If SetApp shows "Arc Fault Detected" (AFCI), do NOT restart the system repeatedly. AFCI is a safety protection indicating a potential dangerous condition. Isolate the DC and AC switches and contact a qualified engineer immediately.
5-step guide to SolarEdge red light diagnosis
Work through these steps in order. The fault code from SetApp or the monitoring portal is your key to understanding the exact issue.
Observe the LED pattern — solid or flashing?
Look at the red light on the inverter's LED panel. Is it:
The inverter has a persistent fault and has stopped producing. This requires investigation or intervention.
The inverter has a transient fault and is attempting recovery. Often clears automatically in 5–10 minutes.
In both cases, immediately open SetApp or the monitoring portal to find the exact fault code — this will tell you the cause.
Check SetApp or monitoring portal for the fault code
Open SetApp (via Bluetooth) or the online monitoring portal (monitoring.solaredge.com). Look for the Alerts, Status, or Error Code section. Write down the exact code. Common red-light codes are:
Note: If no fault code appears in SetApp but the LED is red, try closing and reopening the app, or refreshing the monitoring portal.
Identify which LED is red — DC, communication, or AC/grid?
SolarEdge inverters have three LEDs: DC (usually leftmost), Communication (middle), and AC/Grid (usually rightmost). Each turns red when that system has a fault. Look at the inverter panel and note which LED is red:
For grid faults (flashing red, G-codes) — wait and monitor
If the monitoring portal shows a grid voltage or frequency code (G70–G99) and the red light is flashing, this is usually a brief grid quality issue. The inverter is designed to disconnect if grid voltage goes outside safe limits (typically 207–253V for single-phase UK) — this is a safety feature. Here's what to do:
Do NOT restart the inverter repeatedly if you see a grid fault code — wait for it to recover naturally.
For AFCI faults (arc fault) — DO NOT restart — ISOLATE IMMEDIATELY
If SetApp or the portal shows "Arc Fault Detected" or P700/P701, this is a safety event, not an arbitrary trip. Arc fault detection (AFCI) means the inverter detected abnormal current patterns on the DC side — typically a damaged cable, corroded connector, or failed optimiser. Do not attempt to restart or reset the system.
AFCI faults require on-site investigation to identify the underlying wiring or component issue. Repeated resets without fixing the cause can lead to further damage or safety risks.
How SolarEdge LED status works
SolarEdge inverters use three LED indicators on the front panel, each representing a different system: DC power, internal communication, and AC grid connection. When operating normally, all three are green. A red light on any of these indicates a fault in that system. The monitoring portal or SetApp provides the specific fault code — the LED colour and pattern narrow the category, but the code tells you the exact problem.
The key distinction is between transient faults (flashing red) and persistent faults (solid red). Flashing red usually means the inverter is attempting recovery — most often from a brief grid quality dip. Solid red means the fault is persistent and the inverter has stopped producing. A solid red light that doesn't clear within 10–15 minutes requires investigation.
Arc Fault Circuit Interrupter (AFCI) is a critical safety feature. Unlike other fault codes, arc faults should never be ignored or reset repeatedly. AFCI detection means the inverter has identified abnormal current patterns consistent with an arc in the DC wiring — a serious electrical hazard. The system stops producing to prevent further damage. Investigation and repair by a qualified engineer is mandatory.
