***If you've purchased an EG4 18kPV Inverter through Signature Solar, be sure to use the customer code 'Signature' when setting up the monitoring system!

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.
