Tariff Compatibility
Sungrow works with the following UK export tariffs (see our best Octopus tariffs for solar guide):
- Octopus Flux (compatible with Sungrow batteries)
- Outgoing Fixed
Strengths
- Excellent value, hybrid inverter + battery compatibility at string-inverter prices
- Wide model range fits most UK homes and commercial systems
- Compatible with third-party batteries (BYD, LG, Pylontech) in addition to Sungrow's own
- Strong manufacturing scale drives reliability and parts availability
Weaknesses
- Outside the Intelligent Octopus Flux approved list, so no hands-free peak-rate exporting
- Less shading resilience than SolarEdge/Enphase panel-level architectures
- App is functional but thinner on panel-level detail than SolarEdge or Enphase
Who Sungrow Suits Best
Standard UK installs on unshaded roofs, homeowners wanting hybrid-ready future-proofing without paying Enphase or SolarEdge premiums.
When to Avoid
Your roof has significant shading or you want panel-level monitoring, a string inverter without optimisers will lose output at the shaded panels.
Popular Models
- SH5.0 RS / SH6.0 RS (single-phase hybrid)
- SG5.0RS (standard string)
- SH10RT (three-phase hybrid)

How much does a Sungrow inverter cost in the UK?
Sungrow hybrid inverters typically cost £1,200–£2,200 installed. The SH5.0 RS (5 kW single-phase hybrid) is the most popular UK residential model and sits around £1,400–£1,700.
What batteries work with Sungrow?
Sungrow inverters pair with Sungrow's own SBR and SBH battery ranges, plus BYD, LG and Pylontech depending on model. Compatibility is broader than most hybrid brands.
