Fantastic support. We have a Givenergy system where one of our batteries was not working. Ronald successfully helped us get it back up. His perseverance was amazing….and it shows what REAL customer service means. Can’t thank you enough Ron!
⭐⭐⭐⭐⭐ Absolutely Outstanding Service! My GivEnergy system had completely gone down, and unfortunately I was getting absolutely no support from either the original fitter or the supplier. I was left completely stuck with a system that wasn’t working. I contacted Solar Tech Support and they were absolutely brilliant from start to finish. They quickly got to the bottom of the problem, knew exactly what they were doing, and managed to get my entire system back up and running. Hands down, these guys are absolute experts in their field. The level of knowledge, professionalism and customer service was exceptional, especially when I’d already been left without any support elsewhere. If you have a GivEnergy system and you’re struggling with an issue, don’t hesitate to contact Solar Tech Support. I honestly can’t recommend them highly enough. 5 stars all day long! 🌟🌟🌟🌟🌟
Ronald was great to help me sort out my giv energy inverter issue since company has gone bankrupt in april 26.
Great service in supplying and fitting an additional GivEnergy battery. Went the extra mile in managing to fit the battery in to a difficult space.
⭐⭐⭐⭐⭐ 5-Star Review – Solar Tech Support Installing solar panels is only the first step! To get the best possible performance and maximise your investment, you need to make sure your system is configured correctly and all settings are properly optimised. Solar Tech Support did exactly that for me, and I couldn't be happier with their professional service!** Their knowledge, expertise, and attention to detail helped me optimise my solar system to get the most out of it. If you already have solar panels and battery storage, I highly recommend contacting Solar Tech Support for professional advice, system optimisation, and technical support. Don't just install solar panels – make sure you're getting the maximum benefit from your investment! ⭐⭐⭐⭐⭐ Highly recommended! Thank you, Solar Tech Support, for your excellent service!
What an amazing service. They got my solar inverter back up and running after a firmware update went wrong. It is a breath of fresh air to deal with such a professional company.
Every fault below has a proven diagnostic path. Book a diagnostic if you're unsure where to start.
Hanchu hybrid inverter connected but battery stays flat overnight despite an Octopus or time-of-use tariff. Most often a TOU schedule configuration error in SolarMan — charge window not enabled, grid charge toggle off, or SoC target already met.
See diagnostic guide →Hanchu inverters are configured via SolarMan's TOU schedule. Common issues include charge windows offset by BST/GMT, the grid charge enable setting being toggled off, or peak shaving settings overriding the schedule. We configure the full TOU schedule remotely.
See diagnostic guide →Hanchu LV batteries communicate with the inverter over CAN bus. A BMS comm fault means the inverter can't read the battery state, which causes it to stop charging or discharging. Can be caused by a loose CAN cable, incorrect BMS pairing, or a battery firmware mismatch.
See diagnostic guide →Battery fully charged but not powering the house during peak times. Often caused by a discharge schedule not configured in SolarMan, or the minimum SoC threshold being set too high. EPS/backup mode must also be correctly configured if backup power is needed.
See diagnostic guide →Hanchu hybrid powered but not generating. Check SolarMan for DC input voltage — if zero, check DC isolators and PV string connections. A string fault or MPPT tracking error can stop generation while battery and grid functions continue normally.
See diagnostic guide →Hanchu inverters comply with G98/G99 and will disconnect if grid voltage or frequency goes outside permitted limits. The inverter reconnects automatically once conditions normalise. In areas with many solar installations, repeated trips may need export limiting to prevent instability.
See diagnostic guide →Hanchu hybrid inverters support EPS (Emergency Power Supply) mode but it requires a dedicated EPS output wiring circuit and must be enabled in settings. If the house lost power during a grid outage, EPS may not have been commissioned correctly during installation.
See diagnostic guide →Hanchu uses the SolarMan platform (SolarmanPro) for monitoring. If the app shows offline, the inverter's WiFi datalogger has lost connection, common after a router change or firmware update. The system usually keeps running, but offline doesn't prove it, so check the inverter's own screen.
See diagnostic guide →Hanchu dataloggers require 2.4GHz WiFi. Many reconnection issues after router upgrades are caused by the router defaulting to 5GHz or combined band steering. Start with our general WiFi checks. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting.
See diagnostic guide →We review SolarMan data, TOU schedules, BMS logs, and error history to identify the exact fault without a site visit.
We configure your Hanchu charge and discharge schedule from scratch for Octopus Agile, Intelligent, Go, or Flux. Most configuration faults resolved in a single remote session via SolarMan.
EPS circuit verification, CAN bus cable checks, BMS pairing, DC fault location, and component replacement for Hanchu inverters and Blade LFP batteries.
Hanchu ESS is a Chinese energy storage manufacturer producing hybrid inverters and LiFePO4 (LFP) battery systems for the residential and light commercial market. Their UK range includes single-phase hybrid inverters — the HC-3.68KW-HY, HC-5KW-HY, and HC-6KW-HY — paired with Blade LFP battery modules in capacities from 3.2kWh to 9.4kWh per unit. The inverters carry an IP66 rating, a 12-year inverter warranty, and a 10-year battery warranty. Blade LFP chemistry offers a high 95% depth of discharge, making nearly all the stated capacity usable in daily cycling.
Monitoring and schedule configuration is handled through the SolarMan platform (SolarmanPro for installers, the SolarMan app for homeowners). The most common support queries we handle for Hanchu systems are: Hanchu battery not charging overnight, Hanchu SolarMan offline, Hanchu BMS communication fault, Hanchu grid disconnection, and Hanchu Octopus tariff setup. Hanchu systems are distributed in the UK through companies including Powerland and Solar Battery Group. STS provides independent support — not affiliated with Hanchu ESS.
STS supports all major inverter and battery brands — not just Hanchu. If you have a mixed-brand system (e.g. Hanchu inverter with Lux or Dyness battery), visit the brand hub.
