eVault Max 18.5kWh Lithium Ferro Phosphate (LFP) Installation

The Storage Capacity and total available Amperage are
increased by the parallel arrangement. The following
illustration shows how to connect multiple batteries in
parallel. Please note the overall Voltage is not changed.
The available Amperage from the system has been
doubled.
Parallel wiring
CAUTION! For parallel connecting: Maintain identical wire length and wire construction from each
Fortress Power Battery terminal to the common bus. If you parallel more than 4 units, a battery combiner
is highly recommended.
Please follow the procedure to parallel eVault Max batteries
