Achieve Scalability

When relying on the internal integrated busbars, up to 3 batteries are supported in parallel when connected to a single inverter or 4 batteries in parallel when connected to 2 inverters, or up to 5 batteries in parallel when connected to 3 inverters. See section 7.2 in the PowerPro manual for more information.

Systems with more batteries than these configurations are still possible (Such as the 5:1 configuration pictured above). But, require the use of an external fused positive busbar and an unfused negative busbar rated at a minimum of 200A per battery. Each fuse should be a maximum of 250A. Alternatively, larger systems could rely on the 18kPV’s ability to draw from different battery packs while still paralleling inverters rather than utilizing external busbars.
