What the Anchor looks like where it lives
5.12 kWh of usable LiFePO4 storage, configured for daily depth of discharge and finished for indoor installation. Pairs with single-phase hybrid inverters from 3 to 8 kW. Up to sixteen units run in parallel for households that need more headroom.
The finish is intended for a room people use rather than a plant room. The status display shows state of charge, voltage, current and cell temperature, so you can see what the system is doing without an app or a login.

Where it fits
The sites this cabinet is built for
The 10 marla home and the apartment
An evening of load shedding without the lights flickering. The fridge, the router, the security cameras and the ceiling fans keep running.
The home office and the small clinic
Computer, monitor, printer and Wi-Fi stay live through unannounced outages. A clean transition keeps the work session from crashing.
The expanding household
Start with one cabinet. Add a second when the load grows. Up to sixteen units in parallel without changing the inverter.
The daily pattern
Why this cabinet earns its cost after sunset
Your roof produces in the middle of the day. Your household spends most of its power between sunset and midnight. Without storage the surplus goes to the grid for about PKR 11.33 a unit and comes back at PKR 37 to PKR 55.
The Anchor holds the midday surplus so the evening runs on your own power instead of bought power. That price gap, not the generation figure, is what pays for the cabinet.
