Combine solar panels with battery storage and move a step closer to energy independence

Capture and store the spare energy from solar panels.
Charge your batteries with off peak tariffs.

Battery & Energy storage solutions

Make the most out of your spare solar energy capacity by combining your solar panel system with devices such as a battery storage system and a power diverter such as the MyEnergi Eddi. Take a step closer to energy independence!

A solar system can sometimes produce more power than is required, particularly during summer months. The spare power would normally push onto the local grid for a small amount of compensation, known as the Solar Export Guarantee or SEG for short, for qualifying MCS accredited installations. A battery storage system can capture the excess and provide the maximum value for your home grown kWh.

Several grid energy providers, such as Octopus and EON, offer ‘off-peak’ tariffs. These were also known as ‘Economy 7’ tariffs. These were used to charge up electric storage heaters overnight. It is now more common to use off-peak tariffs to charge up electric cars. They can also be used to charge up a battery storage system with cheap electricity and this is fed back into the house during the peak hours. Most reputable battery storage systems come with an app to control the battery system and set the off-peak timers from a mobile phone.

Energy storage terminology

Usable capacity

Capacity is quoted in kWh of storage power. Batteries do not fully discharge to ensure there’s no damage caused to the battery. Usable capacity is the practical amount of power your battery will deliver.

Power Output

Power output is the amount of power that can be delivered at any one time. It is the rate at which the battery will discharge. This is important to know to avoid drawing power from the grid during heavy usage.

Cycles

A cycle is one complete discharge of the battery. This is linked to the warranty period, which is usually quoted in years and / or number of cycles.

Battery Technology

Lithium Ion and Lead Acid are the two most popular battery technologies. The key difference is the depth of discharge, lifespan and price is lower for lead acid technology batteries.

Solar and battery systems and power cuts

Most solar and battery systems are designed to be grid tied, therefore won’t work in the event of a power cut. However, if this feature is key to your requirements, Climate Force will design this feature into your system.
