Product FAQ

Horizontal Modular Off-Grid ESS Battery

What makes this horizontal modular design ideal for RVs and camper vans?

In camper vans and RVs, vertical space is at a premium, while low-profile areas under passenger bench seats, beds, or false floors remain underutilized. With heights as low as 160mm to 200mm, these horizontal modules slide directly into under-bench compartments while keeping the vehicle's center of gravity low and stable.

How are the modules stacked safely in off-grid setups?

Each module chassis features precision locating corner recesses and high-traction rubber feet. Modules stack securely up to 3 to 4 layers high without external racking, saving floor space while maintaining stable airflow channels between units.

Can 24V and 48V models be mixed in the same system?

No. Systems must use batteries with identical nominal voltages (either all 25.6V or all 51.2V). However, units of the same voltage (e.g. multiple 48V modules) can be connected in parallel to scale overall energy capacity.
