Electrical System Upgrade
This client had a system that would drain the starter battery and could not power the inverter or air-conditioning system without shutting down. They wanted to upgrade the system in the most affordable way to remedy these issues. We installed an additional battery, battery monitor, larger wiring, fuses, and a ignition switched B2B charger to isolate the house and starter batteries.
A new B2B charger was installed with an ignition wire to mitigate the phantom load. The battery bank was sized appropriately for the loads and size specific fuses and cable were installed. The previous wiring had evidence of heat damage on the sheathing from being undersized and the system was using thermal-magnetic breakers inappropriately.
Before: The current system was powered by a battery that could not support the 3000w inverter or the air conditioner, causing the battery to shut off. Additionally, there was no battery to battery charger so the "house" system would drain the starter battery over time.
