08 Solutions
Pick your kind of project: what goes into it, what to ask, and how we quote.
For homes
Panels on the roof, a hybrid inverter and a battery. By day the house runs on its own power. In an outage the essentials keep going. In the evening you buy less from the grid. We supply the equipment, and a partner installer near you designs and fits it.
Your installer chooses the exact combination for your roof, your connection and your consumption.
With a hybrid inverter and a battery, yes, for the circuits your installer connects to the backup output. Typically that means the fridge, the boiler, the router, lighting and a few sockets.
The panels are rated from −40 °C. The DH-WLL010D1 battery heats itself and keeps discharging down to −15 °C. Batteries rated IP20 belong indoors.
Yes. The DHLV-LFP-5000 goes up to six units in parallel, and the all-in-one systems take extra battery packs later.
For businesses
A factory, a warehouse, a farm or a shop uses most of its power in daylight, which is exactly when the panels produce. A rooftop plant cuts the bill. Storage cuts the peaks and keeps critical loads running when the supply fails.
Your yearly consumption and the peak demand from your electricity bill, the roof or land available, and the connection point. We send back the kit with datasheets and certificates. We supply the equipment. Installation is done by your EPC contractor.
For solar parks
For developers and EPC companies building ground-mounted parks and storage in Romania.
Datasheets and IEC certificates come with the offer. Ask us for the documents your bank or your technical adviser needs.
