Blue Electrics installs Sunsynk hybrid inverters for homes and businesses across South Wales. Sunsynk has quickly become the installer's favourite hybrid platform in the UK for one simple reason: it works with almost any battery on the market, delivers genuine off-grid capability, and offers a level of configuration flexibility that fixed-ecosystem systems can't match.
Why we install Sunsynk
1. Battery compatibility second to none
Most hybrid inverters lock you into a single battery brand. Sunsynk doesn't. The platform supports a huge list of compatible batteries — Pylontech, BYD, BSL, Dyness, Hubble, Fortress, and dozens more — which means you can choose the battery that best fits your budget, warranty preference, and capacity needs without being tied to a proprietary ecosystem. If you ever want to expand or replace the battery in future, your options stay open.
2. True off-grid / resilience mode
Sunsynk inverters are designed with genuine off-grid capability. When the grid goes down, Sunsynk switches to battery backup fast enough that sensitive electronics don't reboot. Its essential loads port lets you designate specific circuits (fridge, freezer, lighting, Wi-Fi router) to keep running during outages while other loads stay off the battery. For rural South Wales customers where grid outages happen, this is a major win.
3. Hybrid ranges for every system size
The Sunsynk range we install covers every domestic scenario:
- Sunsynk Ecco 3.6 kW / 5 kW — perfect for small-to-mid domestic systems on single-phase supply
- Sunsynk 8 kW / 12 kW — larger homes, higher consumption, or homes wiring in EV chargers alongside solar
- Sunsynk three-phase — farms, workshops, and light-commercial properties
4. Excellent monitoring and app
The SunSynk Connect app shows real-time generation, battery state of charge, consumption, and grid flow. Historical data is granular down to the minute. You can set time-of-use charging schedules (handy for Octopus Agile, Octopus Go, or Cosy tariffs) directly from the app, and remote firmware updates keep the unit current.
5. Integrated EV charging and heat-pump support
Sunsynk plays well with EV chargers and heat pumps — you can prioritise charging your EV from solar, dump excess solar into a hot-water immersion via a smart diverter, or run a heat pump preferentially from battery during peak tariff windows. This is how you stack up savings on a modern home.
Flagship Sunsynk inverters we install
Three Sunsynk models cover the vast majority of UK domestic and small-commercial installs we quote.
Sunsynk Ecco 5 kW
5 kW single-phase hybrid · 48 V battery bus
Our most-specified Sunsynk. The sweet spot for a typical South Wales 3-bed with 4–6 kW of PV and 10–15 kWh of battery. Excellent value, a built-in touchscreen, and compatibility with every battery we commonly fit.
Sunsynk 8 kW / 12 kW Hybrid
8 kW / 12 kW single-phase hybrid · high-voltage battery options
For larger homes, higher consumption, or properties that want to run an EV charger and heat pump alongside solar. Beefier generator input and a larger continuous load capability makes these the ones to reach for when simple won't cut it.
Sunsynk Max 16 kW Three-Phase
16 kW three-phase hybrid · farms & light-commercial
Our go-to for farms, workshops, and small commercial sites in the Welsh valleys. Genuine off-grid capability at scale, proper three-phase handling, and modular batteries that can be sized to the site.
Warranty and support
Sunsynk inverters come with a 10-year manufacturer warranty as standard (extendable to 15 years). As MCS-certified installers, we handle the registration, DNO notification, and first-line technical support directly — if anything goes wrong, you call us, not a call centre.
Who should choose Sunsynk?
If you want maximum flexibility, future-proof battery options, real resilience against grid outages, or a system that will easily expand over time — Sunsynk is almost always our first recommendation. It's particularly well-suited to:
- Rural properties where grid reliability matters
- Homes planning to add an EV charger or heat pump within the next 5 years
- Customers who want to run time-of-use tariffs to maximise savings
- Anyone who values long-term hardware flexibility over brand loyalty
