How the EUREKA L off-grid kit works
The solar panel charges the battery through the MPPT Triron 30A controller, which maximises yield even in overcast conditions and protects the battery from overcharge and deep discharge. The stored energy directly powers 12V DC loads (LED lights, pumps, surveillance systems) or, by adding a small inverter, 230V appliances. The system runs on full self-consumption, with no grid feed-in and no paperwork.

Frequently asked questions
What is the 400Wp EUREKA L kit suitable for?
It is ideal for cabins, country houses and remote sites where you need to power LED lights, a pump, a low-consumption fridge or small 12V appliances. With an inverter you can also run modest 230V loads.
How much energy does it produce per year?
Estimated yield ranges from about 480 kWh in northern regions up to 650 kWh in southern and sunnier areas, depending on solar irradiation and panel orientation.
Do I need an inverter to use 230V devices?
Yes. The kit directly powers 12V loads; for 230V appliances you need to add an inverter sized to the power of the devices you want to connect.
Does the kit require permits or paperwork?
No. As a standalone self-consumption system it does not feed energy into the grid and requires no notification to the network operator.
Can I expand the system later?
Yes. The 30A MPPT controller lets you add PV power and storage within the limits of the 12V system; for larger needs we recommend the 24V EUREKA XL model.
