Home energy, built for your channel
Woolii equips residential solar installers and energy distributors with a branded home-energy system: LiFePO4 storage, solar, inverters and off-grid kits with transparent specifications and compatibility support.
One brand, the whole energy system
Batteries, solar, inverters and complete off-grid kits — engineered to work together, sold through your channel.
IP65 OUTDOORStorage Wall Series — Wall-Mounted LiFePO4 Home Battery (2.56–14.34 kWh)
Wall-mounted LiFePO4 home battery in four capacities from 2.56 to 14.34 kWh (48 V / 51.2 V). Slim wall-hung housing, safe iron-phosphate chemistry, parallel expansion, and an IP65 outdoor option — engineered for everyday energy independence.

Every Woolii decision starts from the same question: would we hang this on our own wall?
Lithium iron phosphate cells — the most thermally stable home-storage chemistry. No cobalt, no compromise on safety margins.
Cycle life stated with its test conditions. Capacity stated at usable depth of discharge. If a number is on our datasheet, it was measured.
A slim wall-hung housing that installs in tight spaces, with parallel expansion when the household grows.
IP65 outdoor option, standard mounting pattern, and communication with mainstream hybrid inverters over CAN and RS485.
Grow with a brand your customers can trust
Woolii sells through partners, not around them. We build the product and the brand; you own the customer relationship.
Clear regional agreements — we don't sign three dealers on one street.
Transparent lead times and tiered pricing, quoted within 24 hours.
Datasheets, installation guidance and compatibility support direct from our engineers.
Straight answers on home energy storage
Sizing, shipping, grid rules, chemistry — written for the people who buy, install and live with home batteries.
PERC vs TOPCon vs bifacial — how to choose solar panels for your home
An engineer's guide to the three panel technologies that matter for a home: mono PERC, N-type TOPCon and bifacial. What each does well, which roof and budget suits which, and where flexible, foldable and snow-melting panels fit in — with a shortcut to a sized design.
Read the guide →Off-grid, hybrid or backup — which home energy system is right for you?
Before you compare batteries and inverters, decide what the system is actually for. This guide defines the off-grid, hybrid and backup scenarios, shows who each is for, and walks through the equipment, cost and complexity differences from a European starting point.
Read the guide →How much home battery storage do you actually need?
A practical engineering guide to sizing home battery storage: how to estimate your daily kWh, decide how long you want to run on stored energy, and match capacity to your off-grid, hybrid or backup goal — with a worked German-household example.
