SOFAR PowerAll 5kW Hybrid Inverter and Battery Storage System (5.12 kWh - 15.36 kWh)

Take control of your solar energy with the SOFAR PowerAll hybrid inverter and battery storage system. Choose from 5.12kWh, 10.24kWh or 15.36kWh of battery storage to suit your home and energy requirements.

The SOFAR PowerAll combines a powerful 5kW single-phase hybrid inverter with modular, high-voltage lithium iron phosphate (LiFePO4) batteries. Designed for both new solar PV installations and compatible battery storage upgrades, it allows you to store excess solar energy for use when your panels aren't generating.

Its sleek, stackable design provides an integrated energy storage solution without the need for separate wall-mounted batteries.

Choose Your Battery Storage Capacity

Every package includes one SOFAR ESI 5K-S1 5kW Hybrid Inverter, with your choice of battery capacity:

All capacities are nominal battery storage capacities. Actual usable energy will depend on system configuration and operating conditions.

Important: storage capacity versus power output. The ESI 5K-S1 inverter has a 5kW rated output, while each BTS 5K battery module has a 2.5kW rated output. The one-battery option may therefore deliver less than 5kW when operating from battery power alone; available power depends on the number of batteries and complete system configuration.

Why Choose the SOFAR PowerAll?

• 5kW hybrid inverter – manages solar generation, battery charging and household energy use.
• Expandable battery storage – choose the capacity that suits your home, with the flexibility to expand using compatible modules.
• LiFePO4 battery technology – lithium iron phosphate chemistry designed for reliable, long-term energy storage.
• Dual MPPT solar inputs – supports flexible solar panel configurations.
• Store more of your solar energy – use energy generated during the day later in the evening or overnight.
• Backup power capability – supports a suitably designed backup circuit when correctly installed and configured.
• Smart energy monitoring – compatible monitoring features help you keep track of system performance.
• Space-saving stackable design – inverter and battery modules form a neat, integrated system.

Adding Battery Storage to Existing Solar Panels?

Already have solar panels installed? The SOFAR PowerAll can be configured as part of a compatible retrofit battery storage installation.

An additional SOFAR DDSU666 Smart Meter with CT may be required, depending on your existing solar installation and how the inverter will be configured.

The SOFAR DDSU666 single-phase smart meter with CT (manufacturer part 900020700013-0) is available separately as an optional add-on and is not included in the standard bundle. Some PowerAll systems can use the standard CT-only arrangement without this separate meter.

We recommend confirming the correct meter and CT configuration with your installer before ordering.

Technical Specifications

What's Included?

Your selected package contains:

• 1 × SOFAR PowerAll ESI 5K-S1 5kW Hybrid Inverter — manufacturer part 900.02500001-0
• 1, 2 or 3 × SOFAR BTS 5K 5.12kWh Battery Modules, depending on your selection — manufacturer part 930.00400002-0 per module
• All standard system components and accessories needed to assemble the selected PowerAll stack on a suitable flat floor, including its floor-standing base/top-cover arrangement and associated stacking hardware

Ready for flat-floor assembly: This bundle is supplied with the components required for a standard floor-standing PowerAll stack on a suitable level surface. You do not need to purchase a separate base/top-cover kit for that standard arrangement.

Not included: Solar PV panels, the optional DDSU666 smart meter, site-specific electrical cabling/protection or professional electrical installation, unless separately agreed. Floor suitability, required clearances, grid connection, safety protection and commissioning must be checked by the installer.

The system must be installed and commissioned by a suitably qualified installer. Please confirm your chosen configuration and any additional required accessories before purchasing.
