Battery Storage
Battery storage has become crucial for increasing solar energy use, especially after the removal of the FIT subsidy. With affordable systems now available, excess energy generated during the day can be stored for use at night or during peak demand such as when people get home from school and work, helping to reduce electricity bills and maximise self-consumption.
Battery storage is not just ideal for new solar installations, it can also be added to existing systems.
SogoSolar has been installing battery systems since 2016, helping customers cut their electricity bills by up to 75%. We offer only high-quality products from top international manufacturers, with whom we have long established relationships and have been accredited.
Most systems come with a 10 year warranty and all come with a comprehensive web based monitoring platform that enables you to monitor and manage the system.
There are a wide range of Solar Storage options on the market and SogoSolar would be pleased to give you a no obligation consultation on battery storage solutions from the following leading manufacturers:

SolarEdge Home Battery
The SolarEdge Home Battery 400V is a high-performance energy storage solution that is natively supported into the SolarEdge ecosystem, it stores excess solar energy generated during the day for use in the evening or during power outages. Its advanced lithium-ion technology ensures reliable, long-lasting performance while enabling greater energy independence and efficiency.
Optimized for Efficiency, Built for the Future
Compact, scalable, and easy to install, the SolarEdge Home Battery 400V is perfect for homeowners looking to reduce energy costs and rely less on the grid. It supports time-of-use optimisation, backup power capabilities, and full system monitoring via the SolarEdge app.
Tesla Powerwall
The Tesla Powerwall is currently the best known battery storage solution for residential and small commercial applications. It looks great and with its 13.5 kWh of storage capacity is big enough for most UK residential applications. The Tesla Powerwall can also provide back-up power in the event of a grid outage.
One of the main features of the Tesla Powerwall 3 is it’s ability to be installed as a DC coupled system i.e. directly connecting and charging the battery with DC power from solar panels. This eliminates the need for a separate inverter and reduces power conversion losses, increasing overall system efficiency
SogoSolar Ltd is proud to be an accredited Certified Installer and has been installing the Tesla Powerwall since 2016.
Enphase
Enphase is headquarted in California, USA. Enphase designs and manufactures software-driven home energy solutions that span solar generation, home energy storage and web-based monitoring and control.
The AC coupled IQ Battery 5P is a key component of the Enphase Storage System which uses unmatched innovation to create a modular, safe solution for the home delivering the highest lifetime value.
SOLARWATT
Solarwatt, a German company headquartered in Dresden, has partnered with the BMW Group to develop the Battery Vision—an advanced home energy storage system utilising state-of-the-art technology. This collaboration merges BMW’s expertise in battery technology with Solarwatt’s proficiency in solar energy solutions, offering a reliable and efficient means to store solar power for residential use.
The Solarwatt Battery Vision is fully compatible with the rest of Solarwatt’s product range and is managed by the Solarwatt Manager Flex which controls charging and discharging to ensure an optimal use of the available PV power and / or time-variable power grid tariffs.
Sonnen Battery
Sonnen are a German manufacturer and the leading European manufacturer of grid tied residential battery systems. Sonnen battery systems are modular and as such you have a choice of storage capacity ranging from 5 kWh to 15 kWh.
Sonnen also offer a Hybrid unit which combines the inverter for a solar PV system together with the battery for an all-in-one storage system. Hence just one ‘box’ needs to be installed.
We are an Accredited Installer for Sonnen and have been installing Sonnen battery systems since 2017.
We also installed the first 3 Sonnen Hybrid systems in London in 2018.
