Wrenstead Store 1 – 1.024kWh Battery Storage

Store 1 is the compact entry configuration for households that already have a compatible solar system and want to start adding battery storage.

The system combines:

1 × H1600 Smart Solar Hub
1 × L1024 LiFePO4 battery module
1.024kWh nominal battery storage capacity
Low-temperature battery heating
Approx. 95W heating power
App monitoring
User-configurable energy schedules

Store 1 does not include solar panels or an LS-800Mi microinverter.

If you already have solar, compatibility should be checked before ordering.

Launch price: £529

Wrenstead Store 2 – 2.048kWh Battery Storage

Store 2 provides twice the battery capacity of Store 1 while retaining the same H1600-based system architecture.

The system combines:

1 × H1600 Smart Solar Hub
2 × L1024 LiFePO4 battery modules
2.048kWh nominal battery storage capacity
Low-temperature battery heating
Approx. 190W total heating power when both battery modules require heating
App monitoring
User-configurable energy schedules

Store 2 is intended for customers with compatible existing solar who want greater storage capacity than the 1.024kWh Store 1 configuration.

Launch price: £799

Wrenstead Solar + Store 2 – 960W Solar & 2.048kWh Storage

Solar + Store 2 is the complete Wrenstead configuration for customers who are starting without an existing solar system or want the matched solar, microinverter, energy-management and storage components supplied together.

The system combines:

960W solar generation capacity
1 × LS-800Mi 800W microinverter
1 × H1600 Smart Solar Hub
2 × L1024 LiFePO4 battery modules
2.048kWh nominal battery storage capacity
Low-temperature battery heating

Cold-Weather Battery Charging

All three Wrenstead core system configurations use L1024 battery modules with low-temperature cell heating.

The heating function is designed to protect the battery cells from being charged below their permitted charging temperature.

Below 5°C: battery heating activates automatically when a compatible external charging source is connected.
Below 0°C: external input power is used to heat the battery cells first. The cells are not charged below 0°C.
At or above 0°C: battery charging can begin while heating continues.
At approximately 10°C: the heating function stops and normal charging continues.

The heating energy is supplied by the connected external PV or compatible DC charging input rather than being drawn from the battery's stored energy.

Cold-Weather Feature	Store 1	Store 2	Solar + Store 2
L1024 Modules	1	2	2
Heating Power	Approx. 95W	Approx. 190W total	Approx. 190W total
Heating Start	Below 5°C	Below 5°C	Below 5°C
Battery Charging Begins	At or above 0°C	At or above 0°C	At or above 0°C
Heating Stops	Approx. 10°C	Approx. 10°C	Approx. 10°C

Important: -20°C is the specified lower discharge temperature, not the minimum charging temperature. The specified battery charging range begins at 0°C.

Already Have Solar Panels?

If your home already has solar panels, Store 1 or Store 2 may provide a route to adding battery storage without purchasing another complete solar package.

The correct configuration depends on your existing solar panels, inverter or microinverter, voltage and current characteristics, and the proposed electrical connection.

Check your solar and storage compatibility

1.024kWh or 2.048kWh Battery Storage?

The principal difference between Store 1 and Store 2 is battery capacity.

	Store 1	Store 2
Battery Modules	1 × L1024	2 × L1024
Nominal Storage Capacity	1.024kWh	2.048kWh
Low-Temperature Heating	Included	Included
Approx. Heating Power	95W	190W total
H1600	Included	Included
Launch Price	£529	£799

Actual usable energy requirements vary by household and by the appliances or loads you intend to support. We therefore do not recommend choosing a battery solely from headline capacity.

How Wrenstead Energy Scheduling Works

Wrenstead systems support app monitoring and configurable charging and energy-use schedules.

You can configure preferred time periods according to your household routine or electricity tariff.

The system does not automatically retrieve live dynamic electricity tariffs or automatically select the cheapest electricity period.

Check Compatibility Before Ordering

Compatibility is especially important when adding battery storage to existing solar equipment.

Before ordering, information that may need to be checked includes:

Solar panel manufacturer and model
Number and power of installed panels
Panel voltage and current
Existing inverter or microinverter
Current electrical configuration
Proposed Wrenstead system

Check Your Solar & Storage Compatibility

Installation & Connection

Connection requirements vary according to the property, existing solar equipment and final system configuration.

Do not assume that the same installation method applies to every UK home.
