Why Growatt? The World's No.1 Residential Inverter
Growatt has been manufacturing solar inverters and battery systems since 2010. With over 4 million installations across 180 countries, they are the global market leader in residential solar inverter shipments. That scale matters: it means proven manufacturing quality, extensive real-world performance data, and competitive pricing that benefits from economies of scale.
For Leicester homeowners looking for dependable battery storage without overspending, Growatt offers the best balance of quality and value. Their UK operation includes a dedicated support team, a distribution centre with stock availability, and a growing network of certified installers — of which Energy Concerns is one.
Growatt's ShinePhone app provides real-time monitoring of your solar generation, battery charge levels, household consumption, and grid import/export. While not quite as feature-rich as GivEnergy's app, it covers everything most homeowners need and is free for the lifetime of the system.

How Growatt Saves You Money
Without battery storage, a typical Leicester solar panel system exports 55-65% of generated electricity to the grid during the day — earning just 4-6p per unit via the Smart Export Guarantee. You then buy electricity back from the grid in the evening at 24-30p per unit. A Growatt battery stores that surplus for evening use, flipping the economics in your favour.

Growatt Battery Storage Without Solar
You do not need solar panels to benefit from a Growatt battery. Many of our Leicester customers install batteries as standalone units to exploit cheap overnight electricity tariffs. On tariffs like Octopus Go (7.5p/kWh overnight), you can charge your Growatt battery at night and use that stored energy during the day when electricity costs 24-30p per unit.
A 10kWh Growatt battery charged overnight on Octopus Go costs approximately 75p. Using that same 10kWh during the day at standard rates would cost £2.40-£3.00. That is a saving of £1.65-£2.25 per day — or £600-£820 per year — from a standalone battery that costs £3,500-£5,000 installed.
Growatt's hybrid inverter design means you can start with battery-only and add solar panels later without replacing any hardware. Energy Concerns designs every installation to be future-proof.
Growatt for Leicester Homes
We have installed Growatt battery systems across Leicester and the wider East Midlands. The 5kWh unit is popular with budget-conscious homeowners in Leicester's semi-detached streets — Aylestone, Beaumont Leys, Braunstone, Evington, and Knighton — while the 10kWh model suits the larger detached properties found in Oadby, Wigston, and the surrounding villages.
Growatt works seamlessly with the solar panels we install — AIKO, Canadian Solar, and Trina Solar — and integrates with SolarEdge optimised inverter systems. Whether you are adding a battery to an existing solar system, installing solar and battery together, or fitting a standalone battery for tariff arbitrage, Energy Concerns will design the optimal Growatt solution for your home.
