The Ultimate All-in-One Off-Grid Power System for Campervans and Motorhomes

Introducing the Eberspächer Zeliox NEO 4000, an advanced all-in-one off-grid electrical power system designed specifically for campervans, motorhomes and leisure vehicles.

Unlike traditional electrical installations that require multiple separate components, extensive cabling and complex programming, the Zeliox NEO 4000 integrates a high-capacity lithium battery, pure sine wave inverter, intelligent DC-DC charger, MPPT solar charger, mains battery charger, AC bypass functionality, power distribution and advanced monitoring into one compact, professionally engineered unit.

The result is a cleaner installation, reduced wiring complexity, improved reliability and significantly faster installation compared to conventional multi-component electrical systems.

Whether you’re powering induction cooking, coffee machines, laptops, air conditioning, televisions or everyday appliances, the Zeliox NEO 4000 delivers dependable off-grid power with intelligent charging from your alternator, solar panels or mains hook-up.

Supplied and professionally installed by Vanbitious, every system is installed, commissioned and tested to ensure optimum performance and long-term reliability.

Why Choose the Zeliox NEO 4000?

While effective, these systems require considerable installation time, additional wiring and increased space.
