This client needed a small solar charging system for DC loads and battery maintenance with a battery monitor to help them regulate energy consumption. What they got was a solar panel kit consisting of two of our SF100 solar panels connected in parallel with our roof mount combiner box. To reduce DC line losses, heavy 6ga wire was routed from the combiner box to the MPPT charge controller and then to the battery bank. Between the most negative battery and all negative connections, we installed a shunt to measure current. The shunt and the charge controller communicate with the Blue Sky IPN Pro monitor to give full system status with Amp-hour precision.
