Sofar Inverter Error Codes
Legacy Sofar ME3000SP ID codes anchored to the official manual, without inferring the same remedies for HYD or later inverter families.
46 of 46 codes
About this fault librarySources · scope
This library is now anchored to the official ME3000SP manual. Sofar products reuse ID-style alarms, but numbering and meaning can shift between ME3000SP, HYD ES/EP and later string or storage families. Do not transfer an ME3000SP remedy to another family without its exact manual; those applicability fields remain deliberately blank. Safety note: owners should stop at recording the code, app status and safely visible conditions. DC/AC isolation, electrical measurements, opening equipment, firmware work and protection-setting changes are licensed-worker tasks. Any shutdown or restart must follow the procedure for the exact model and site; do not use this library as a switching sequence.
- 46 Sofar Solar (Shenzhen SOFARSOLAR): legacy ME3000SP retrofit inverter fault and alarm codes, documented for the trade.
- Compiled from published documentation and field references; Wattbench is independent and not affiliated with Sofar Solar (Shenzhen SOFARSOLAR): legacy ME3000SP retrofit inverter.
- Codes involving DC/AC isolation, wiring or opening the unit are licensed electrical work. Isolate safely and follow AS/NZS procedure.
Resolution text is manufacturer/service context, not permission for an owner to perform electrical work. Stop at visible observations unless the exact product instructions identify an owner control. Isolation, configuration, testing, opening equipment and wiring are for an appropriately licensed worker and, where required, an SAA-accredited person. Where a card says Product fit is unknown, treat it as brand-level guidance and confirm the exact model, role, regional variant, firmware and current manual before acting.

Record the code and allow the battery to recharge under its normal configured mode. Do not alter depth-of-discharge, voltage or charge settings; contact the installer if it recurs.
Installer remedy
Check battery state, configured limits and charging availability against the ME3000SP and battery documentation. Preserve the protection limits and escalate an abnormal or recurring low-voltage condition.

Frequently asked
- Where do these Sofar fault codes come from?
- Compiled from publicly available Sofar inverter and battery documentation and field references, then rewritten for the trade. Wattbench is independent and not affiliated with Sofar.
- Which of these can I clear on site?
- Some clear on their own once grid or environmental conditions return to normal. Anything involving DC isolation, AC switching, wiring or opening the unit is licensed electrical work. Isolate safely, follow AS/NZS 5033 and AS/NZS 3000 procedure and use appropriate PPE before touching a live system.
- The exact code isn't listed. Why not?
- Firmware and model variants differ, and manufacturers revise their code tables. We document the most common ones; for a variant that isn't here, check the unit's current manual or the manufacturer's service portal.
- How current is this reference?
- This reference was last reviewed on 2 August 2026. We revise entries when the underlying manufacturer documentation changes.
