What is a solar battery? A solar battery allows you to use more of the energy being generated by your solar panels. Adding solar panel battery storage to your solar system will further reduce your reliance on an energy supplier, taking your energy savings even further. A solar battery allows you to continue powering your home with renewable solar energy during the evening and at night when the solar panels aren’t able to generate energy. Solar PV panels convert solar energy into usable electricity and, more often than not, they’re producing more electricity than can be used. Without a solar battery, this excess is delivered to the National Grid, this means that you’ll miss out on using the energy yourself and will have to rely on your energy supplier once the sun has set.

Where back-up electricity supply would be one less worry

you need to be looking at an AC coupled system. At the time of writing, we were

only able to find 3 battery systems available in the UK that will keep the lights

on during a power cut.

The Tesla Powerwall 2.0 with the Back-up Gateway.

This updated version of the Powerwall 2.0 comes with a separate unit which looks

like a smaller version of the battery itself and completely islands your home in the

event of a power cut.

The second and much cost effective option is the PureStorage battery system

from Puredrive. Finally, the Samsung SDI can also provide emergency power.

Always check on the manufacturers data sheets ahead of the installation as

power-cut back-up may not be fitted as standard, or just give us a call

Built in back up

You need to be looking at an AC coupled system.

At the time of writing, we were only able to find 3 battery systems available in

the UK that will keep the lights on during a power cut.

The top quality two are, Tesla or PowerDrive

2 - Examples of Solar Batteries with Back-up Power

1- Tesla Powerwall with Back-up Gateway 2

The 13.4 kWh Tesla Powerwall 2.0 has been leading the

international solar battery market for many years but until

recently it did not have the back-up power supply feature.

The company has now released the Tesla Powerwall 2.0

with Back-up Gateway in the UK and Germany.

The new gateway component looks like a small version

of the Powerwall battery and will island the battery from

the grid in the event of a power cut.

In addition to this

New feature, Tesla claims that the battery now has faster

connectivity stronger connection to the monitoring system.

The Powerwall has a 5 kW inverter which could cover a

significant (if not all) of the electrical load in the average

home during a power cut.

Puredrive Energy - Pure Storage

2nd Example of Solar Batteries with Back-up Power

Puredrive Energy PureStorage

Pure Drive is a British designer and manufacturer of

innovative solar storage systems. PureStorage residential

battery is a Hi-Rate 5 or 10kWh LiFePo4 battery which

can both store excess solar energy and provide back

up power in the event of a power cut.

When the system detects a power cut the battery

will automatically power your appliances through a

UPS (Uninterrupted Power Supply)which begins in

less than under 20 milliseconds.

The PureStorage battery is a smart battery and can be

monitored and controlled using a free app or the

website via a mobile device with an internet connection.

PureStorage battery installed inside or outside

If you would prefer to keep the battery outside your

home you can choose to include a weatherproof

outside enclosure.

The PureStorage has options of 3 or 5 kW inverters

with a Purdrive battery of 5 KWh or a 10 KWh,

both options include a 10 year warranty with 6,000 cycles

for your peace of mind.

How much do the best solar batteries cost?

Solar battery prices can range from £500 to over £7,000, before installation which

is likely to cost around £500-£2,000.

Select your Emergency Power Supply circuits “EPS”

It is possible to separate your appliances onto different electricity circuits so that

only the low-energy appliances are powered by the battery.

This is usually a straightforward process which is not costly or complex.

Solar batteries with back-up power

Which is not the same as built into the Solar Batteries

all in one systems such as Tesla Powerwall or PowerDrive

How they work > Switch over switch

Solar batteries with back-up power require the installation electrician install

a relay “switch over switch” into a additional consumer unit, this relay switch

when it detects a power cut would then automatically disconnect your electricity

supply from the grid is referred as slanding.

“EPS” circuits

This relay is installed between your main fuse board

and the incoming electricity incoming electricity supply

allowing you to continue to use your appliances which have been selected

“EPS” for your emergency power supply circuits such as lights /computer /

TV / fridge / during the power cut.
