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.

Sofar Solar has a large UK install base across two distinct product generations — HYD hybrid inverters and the older ME3000SP AC-coupled units. We support both.
Sofar HYD hybrid inverters use SolarMan for schedule configuration. If the battery isn't charging on cheap rate, the TOU schedule likely has the charge window disabled, grid charge toggled off, or the SoC minimum already met. For ME3000SP units, the schedule is set locally on the device — a common source of confusion after router changes.
See diagnostic guide →The Sofar ME3000SP is an AC-coupled BESS managing battery charge/discharge alongside an existing solar system. Common issues: schedule set incorrectly after a power cycle, EPS mode not triggering during a grid outage, battery not communicating correctly over RS485, or the unit being stuck in a fault state requiring a configuration reset.
See diagnostic guide →Sofar HYD hybrids communicate with their paired battery via CAN bus or RS485. A BMS comm fault stops the inverter from reading battery state, preventing charging and discharging. Common causes: wrong battery type selected on the inverter, loose CAN cable, or Pylontech/Dyness protocol mismatch if a third-party battery is paired.
See diagnostic guide →Battery fully charged but the Sofar inverter isn't drawing from it. Check the discharge schedule and minimum SoC threshold in SolarMan. A BMS protection trip will also prevent discharge — check the inverter event log for battery protection errors.
See diagnostic guide →Sofar inverter powered but not generating. Check SolarMan for DC input voltage — if zero or very low, inspect DC isolators and PV string connections. DC isolation faults (G-ISO) and MPPT errors can suppress production while battery functions continue normally.
See diagnostic guide →Sofar inverters comply with G98/G99 and disconnect if grid voltage or frequency exceeds limits. The inverter reconnects automatically. In high-solar-density areas, repeated trips may require export limit configuration. The ME3000SP can also issue grid fault codes related to its AC coupling point.
See diagnostic guide →Sofar HYD hybrids support EPS mode, but it requires dedicated EPS wiring and must be enabled in settings. The ME3000SP also supports an EPS/off-grid mode but is frequently not commissioned for it. If backup power failed during an outage, EPS was likely never set up — or the load exceeded the EPS output rating.
See diagnostic guide →We review SolarMan data, TOU schedules, BMS logs, and error history for HYD hybrid inverters. We also review ME3000SP configuration logs and event history.
We configure TOU charge/discharge schedules for HYD hybrid inverters, or set the direct schedule on ME3000SP units, to correctly use Octopus Agile, Go, Intelligent, Flux, or any other tariff.

Sofar Solar is a Chinese manufacturer with a large UK installed base across two distinct product generations. The ME3000SP was one of the most widely installed AC-coupled battery energy storage systems in the UK between 2016 and 2021 — it retro-fits to existing solar systems to add battery storage and operates independently of the solar inverter. The newer HYD series (HYD 3600–6000 EP) are all-in-one hybrid inverters combining solar MPPT, battery management, and grid connection. Both use SolarMan for monitoring — the same platform used by Sunsynk and Hanchu systems.
The ME3000SP has a large installed base of older units now approaching the 7–10 year mark, and configuration faults or component wear are increasingly common on these systems. For newer HYD hybrid systems, the configuration issues are similar to other SolarMan-based hybrids. Common queries: Sofar ME3000SP not charging, Sofar HYD battery not charging overnight, Sofar SolarMan offline, ME3000SP EPS mode fault, and Sofar battery BMS comm fault. STS provides independent support — not affiliated with Sofar Solar.
STS supports all major inverter and battery brands. Sofar HYD inverters are often paired with Pylontech or Dyness batteries — visit those brand pages for battery-specific guidance.
