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.

A rooftop array makes its power in the middle of the day. A Pakistani household uses most of its power after sunset. Storage moves the orange surplus across to cover the blue evening gap, which is the whole reason a battery pays.

Questions about the Anchor

How long will the Anchor run my house?
A 5.12 kWh cabinet covers lights, fans, refrigeration, router and cameras through a full evening. It will not carry an air conditioning compressor for long, and anyone who tells you otherwise is selling rather than sizing.
Where does it get installed?
On a wall, indoors, near the inverter and the distribution board. It is finished for a room people use rather than a plant room, and the survey settles the position before anything is ordered.
Can I add a second cabinet later?
Yes, up to sixteen in parallel without changing the inverter. Starting with one and adding another as the load grows is a common and sensible pattern, and it is cheaper than buying capacity you will not use for three years.
Is the quoted capacity usable?
It is nominal energy. Depth of discharge is published separately at 95 percent, so multiply the two for the usable figure. Any supplier who will not give you both numbers is quoting a number that cannot be compared.
What does the cycle rating actually mean?
6,000 cycles measured to 70 percent residual capacity. At roughly one cycle a day that is about sixteen years before the pack reaches that threshold, and it keeps working past it with less capacity.
Does it need its own cooling?
No. It is passively cooled and rated to 55 degrees, which covers a Pakistani summer indoors. What it does need is ventilation clearance, which is why the position is a design decision rather than wherever there is a free wall.
Will it work with my existing inverter?
If it is a hybrid inverter from one of the eight brands we have verified, almost certainly. Send us the make, model and firmware and we will confirm before you commit rather than after.
What is covered by the warranty?
Five years replacement plus three years service support, honoured by us rather than by an importer. We assembled the pack, we installed it, and we answer the phone.
