24V off-grid photovoltaic kit with a minimum of 800 Wp, complete and of high quality
The EUREKA XL off-grid solar kit, 800Wp at 24V, stands out for the quality and completeness of its components. With dual panels and dual storage it powers 24V loads or, with an inverter, 230V appliances — ideal for cabins, country houses and sites beyond the grid.
The EUREKA XL off-grid solar kit is a complete standalone system rated at least 800 Wp at 24V, with dual panels and dual storage to power more demanding loads where the grid does not reach. Components selected for quality and reliability deliver a durable, ready-to-use system for cabins, country houses, shelters and remote facilities.

How the EUREKA XL off-grid kit works
The two panels charge the 24V storage through the MPPT Triron 30A controller, which maximises yield even in low light and protects the batteries from overcharge and deep discharge. The stored energy powers 24V loads directly or, through an inverter, 230V appliances. The 24V architecture reduces cable losses compared to 12V and handles higher power. Full self-consumption system, with no grid feed-in and no paperwork.
What the kit includes
- 2 monocrystalline solar panels (min. 800 Wp total)
- MPPT Triron 30A charge controller
- 2 deep-cycle lead-acid batteries 100 Ah

Ideal applications
Powering cabins and country houses in extended use, shelters, small off-grid accommodation, pumping and surveillance systems in areas not served by the national grid.
Frequently asked questions
What is the difference between EUREKA XL and EUREKA L?
The EUREKA XL runs at 24V with 800 Wp and dual batteries (~1200 Wh usable), handling larger consumption and lower cable losses than the 400 Wp 12V EUREKA L, which suits smaller systems.
How much energy does it produce per year?
Estimated yield ranges from about 950 kWh in northern regions up to 1,300 kWh in southern, sunnier areas, depending on solar irradiation and panel orientation.
Can I power 230V appliances?
Yes, by adding a 24V inverter sized to the load. The kit supplies 24V DC directly and the inverter converts it to 230V.
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.
Are the batteries pre-configured for 24V?
The kit includes a connection link to wire the two 12V batteries in series for a 24V system; the connection is simple and documented.
