Premium and reliable solar + battery solutions
The whole street goes dark. Your lights, your ref and your aircon keep running, because the battery took over before you looked up.
The night asks for twelve hours. You get nineteen, and at 6 AM the roof takes over again.

battery
Six units run in parallel on the same wiring, up to 90 kWh and 36 kW. Estates, resorts and farms usually land here. At this size the right answer depends on your building, not on a catalogue.
Quick check
Three taps. You don't need power forever, only until the sun comes back.
Every figure here is an estimate from the approved engineering tables. Yours comes from an assessment, in writing.
Your answer
JANARIX 30
365 nights a year, covered without the grid
Simple by design
Step 1 · Daytime
Solar runs your home and fills the battery. If the roof falls short, the grid quietly makes up the difference.
Step 2 · Night
No noise, no fuel, no smell. Nobody has to go outside and start anything.
Step 3 · Brownout
It switches in under 20 ms. The whole street goes dark. Your Wi-Fi doesn't drop.
The sun runs the house and fills the battery. If the roof falls short for a moment, the grid quietly makes up the difference.
The battery runs the house. Nothing is burning, nothing is running outside, and the grid is sitting there in reserve.
The grid is gone. The battery was already carrying the house, so there is nothing to switch and nothing reboots.
Start where you are
Different buildings, different answers. Pick the one that sounds like your situation and we'll take you straight there.
Start small, grow later
Both builds are made to grow, and nothing inside the house gets rewired to do it. What differs is the size of the step and what happens on the day, which is worth knowing before you buy rather than after.
Standard build · V6000
One more sealed cabinet
15.07 kWh and 6 kW per cabinet. Six run in parallel, to 90 kWh and 36 kW.
Pro build · Mars I Plus
One more battery module
5.12 kWh a module, five on the inverter already fitted, so 5.12 to 30.72 kWh. Past that the next step is a second inverter.
One 5.12 kWh module. On the Pro build, this is the step.
Daylight
Between sunrise and sunset the roof is paying for itself.
After that the battery carries the house, and the street outside has nothing to do with it.

From the blog
What we run into on site, and the questions people actually ask us.
Before you ask
No, and the difference shows up on the first night. A generator has to be started, it burns fuel you have to buy and store, it is loud enough to annoy your neighbours, and there is a gap between the brownout and the moment it runs.
A battery has already switched over before you look up from your phone. There is no gap, no noise, no fuel and no smell.
Then take the battery on its own. It plugs into an ordinary outlet, nothing is drilled and nothing is attached to the building, so no landlord approval is needed and it moves with you. See battery-only options.
Yes, and there are two kinds of step. Adding storage means a battery cabinet on the standard build, 15.07 kWh at a time to about 90 kWh, or a 5.12 kWh module on the Pro build. Output stays where it is either way.
Adding output means a whole second unit. On the standard build that is another V6000, so the battery and the inverter both double. On the Pro build it is another inverter with its own stack. Neither needs anything inside the house rewired.
A free maintenance visit, a performance check, and a written reply within 24 to 48 hours whenever you contact us. If a unit is ever faulty, Marstek's cover replaces it rather than repairing it, and we order the replacement for you. Janarix Care, our membership for scheduled visits and reporting, opens later. Read how we support you after the install.
Our platform partner
Most installers in the region fit unbranded battery racks. We do not. When your power depends on a battery for the next ten years, the name on that battery is something you can check, hold to a warranty, and call about.
