ZYNTRA · Residential ESS
Power That Stays On. Bills That Go Down.
Intelligent LFP battery storage — engineered for safer, quieter, lower-cost living at home.
A ZYNTRA battery keeps your home running when the power doesn’t — and quietly saves you money every day it’s switched on.
Overview
Backup power you stop having to think about.
Most people only think about backup power when it fails them. ZYNTRA is built so you stop thinking about it at all — it just works, in the background, saving you money whether the grid is up or down. And if it ever needs attention, our team comes to you.
Every ZYNTRA battery is backed by a 5-year onsite warranty — not a box you post back and wait on, a person who shows up.
Applications
Built for wherever the power actually needs to stay on.
Mid-size and large homes
Sized up to cover a full evening’s essential load.
Villas with rooftop solar
Pairs with your existing or planned solar inverter.
Home offices
Enough backup to keep a workday running through an outage.
Benefits
Five things that change the day you switch it on.
01
Save More Than You Spend
If you have solar panels, you already know the frustrating part: they make the most power in the middle of the day, right when you’re at work and barely using any of it. And selling that power back to the grid doesn’t pay what it used to.
ZYNTRA stores that extra power instead, and gives it back to you in the evening — exactly when electricity is most expensive. No habit change required. It just happens.
35–55%
Lower monthly bill
Typical reduction for a home pairing rooftop solar with a correctly sized ZYNTRA battery — with no change in habits required.

02
Set It Up Once. Forget About It.
You don’t check on your fridge every day to make sure it’s working — a ZYNTRA battery is built to feel the same way. It learns your home’s routine and the time-of-day power rates, and quietly decides when to charge and when to use its own stored power, all on its own.
Want to check in anyway? A simple app shows you what it’s saved and how it’s doing, whenever you’re curious.
03
Safe Enough for the Room Your Kids Play In
A battery that lives in a hallway cupboard, a home office or a store room has to meet a much higher bar than one sitting in a warehouse — and that’s exactly what ZYNTRA is built for.
Inside, it uses LFP battery chemistry — the same type of battery hospitals and data centres trust, because it stays stable at far higher temperatures than other lithium batteries before there’s ever a problem. There’s nothing to leak, nothing to top up, and no toxic metals inside it.
04
Built to Outlast the House Renovation
Most inverter batteries start losing their punch after a year or two of daily use. ZYNTRA is built for 15 to 20 years of the same routine — charge in the day, power your evening — before it ever drops below 80% of what it could do on day one. A small onboard computer watches over the battery’s health the entire time.
05
Looks Like It Belongs in Your Home
Most backup batteries look like they wandered in from a factory. ZYNTRA doesn’t. It’s finished in a soft matte white with clean, simple lines, sits flush against the wall, and hides all its wiring behind one clean panel. There’s no fan whirring away either — it cools itself quietly.
Evening, on stored sunlight
The system carries the house through the most expensive hours of the day without anyone in the room needing to think about it.
Rooftop solar charges the battery through the day; the app shows exactly where every unit is going.
Technical Specifications
Seven models. One LFP foundation.
Every ZYNTRA home battery is built on the same LFP foundation — the difference between models is simply how much power you need, and for how long. All models come with our 5-year onsite warranty as standard.

FAQs
Frequently asked questions
Yes. It uses one of the most stable battery chemistries available, in a fully sealed unit — nothing to leak, nothing to vent, nothing to worry about with kids or pets nearby.
The ZYN-S100 and S150 are built for exactly that — pair with your existing solar inverter, no extra hardware. The ZYN-H and ZYN-M series are backup-only by design; if solar pairing matters, start from the S-series or talk to a storage expert about the right model.
Years 1–2 are fully covered — parts, labour, travel and logistics, at no cost. Years 3–5 keep labour and logistics free, with any replacement parts billed at cost. Full terms are on the Residential Warranty page.
No routine maintenance. LFP chemistry doesn’t need the periodic servicing lead-acid systems do — the BMS monitors every cell continuously in the background, and there's nothing to top up or replace on a schedule.
Rated for up to 8,000 charge cycles before capacity drops below 80% — at roughly one cycle a day, that's well over a decade of daily use. The 5-year warranty covers the period a manufacturing defect would most likely surface; the chemistry is built to outlast it.
That's what ZyntraPOD is for — battery, inverter and EMS factory-matched into one box, ready to connect.
