Looking for a home battery that can charge your car too?

If you have solar panels and no battery, most of what your roof produces leaves the property at the moment it is worth least to you. Solar battery storage for homes fixes that timing problem: panels peak at midday, households peak morning and evening. Emaldo Power Core stores the surplus and, unlike most home batteries, also charges your car. Battery, inverter, solar connection and a built-in Type 2 charge point sit in one 10.8 kW cabinet, fitted in a single visit, and it works with panels you already own.

FAQ

Why Emaldo Power Core?

Power Core combines battery storage, inverter, solar connection and an electric vehicle charge point in a single cabinet, delivering up to 10.8 kW from LFP (lithium iron phosphate) cells, a chemistry chosen in home storage for its thermal stability. One system, one installation, one app.

Because the inverter is built into the unit, Power Core connects straight to solar panels you already have, across three separate solar inputs. Nothing on your roof needs replacing. Capacity runs from 5.12 to 15.36 kWh across three battery slots, so you can start with what you need now and add more as your household changes. Cabling is concealed inside the unit using Emaldo's SlideOn installation, which keeps the cabinet tidy against the wall and live cables out of reach. It is IP54 rated for outdoor installation and runs under 50 dB, so it does not need a room you were using for something else.

The part that sets it apart is the charge point. A Type 2 connector rated up to 10.8 kW is built into the same cabinet, so there is no second unit on the wall, no separate charger to buy and no additional wiring run. One visit covers storage and car charging together, and the Emaldo app decides whether stored solar goes into the house or the car. For a household weighing up a battery and a charger as two separate purchases, doing both at once is the simpler route. It suits homes with a driveway or a carport. Solar input ranges, grid specifications and full technical detail are in the Power Core data sheet.

Can I charge my car with solar, and how quickly?

Yes, and the charge point is fast enough that a normal day's driving is replaced in about an hour. Your car sets the real limit rather than Power Core, since some models accept more power than others, and the cabinet delivers whatever yours can take.

Charging straight from the panels rarely works well, because the sun is strongest while the car is out. That is the gap the battery closes. Your panels fill the battery during the day, the battery charges the car when it gets home, and the app decides which gets priority.

The saving comes from that swap. Solar you would have exported cheaply at midday goes into your car instead of electricity you buy at the evening price. How much that is worth depends on your tariff and what your export pays.

Can my battery earn money as well as save it?

In some markets, yes, and separately from the savings above. Emaldo Grid Rewards bids your battery's spare capacity into the ancillary services market, the market that keeps electricity supply and demand in balance. Operators pay to have that capacity on standby and pay again when they call on it, typically for 15 to 20 minutes at a time, and Emaldo shares that revenue with you monthly.

Grid Rewards operates in Sweden, Denmark and Finland, and your choice of electricity supplier affects what you can earn. Payments track market prices, so they vary month to month. Estimate your Grid Rewards earnings.

Vicky Eriksson, Account Manager at Emaldo:
”Power Core is our all in one power house. With it, we wanted to make it easier to take control of your home´s energy by integrating solar, battery storage and EV charging in one solution”, says Vicky Eriksson, Account Manager Residential at Emaldo.

Conclusion

So, do you need solar battery storage? If your panels export all day while you buy electricity back after dark, storage is the missing piece. Power Core adds it, and adds car charging in the same cabinet, working with the solar you already have. How much you get out of it depends on your array, your household and your tariff, which is what an installer survey is for. Find an installer near you.

FAQ

What if I already have solar panels?
You keep them. The inverter is built into Power Core, so it connects directly to your existing panels across three solar inputs. The input specifications your installer will need are in the data sheet.

Do I still need a separate EV charger?
No. A Type 2 charge point rated up to 10.8 kW is built into the cabinet, so there is no separate charger to buy and no extra wiring run.

How much battery capacity do I need?
Power Core takes one to three batteries, giving 5.12 to 15.36 kWh. The right number depends on how much you use in the evening and overnight, how large your array is, and whether you charge a car at home. You can add batteries later.

What guarantee comes with it?
Emaldo® guarantees that the hardware will work according to specification if handled according to user guidelines and standards, under a 10-year hardware guarantee. The data sheet sets out the full guarantee terms, including those covering battery capacity over time.

Is a lithium home battery safe?
Power Core uses LFP cells, chosen for their thermal stability, with over-voltage, over-temperature, overload, residual current and surge protection. Cells are certified to IEC 62619 and UN38.3. Installation by a qualified electrician is essential.
