Off-Grid Solar System
The Off Grid Solar (PV) System is a standalone system. This means your system does not get any of its power source from a utility company. Therefore this Solar (PV) System must be designed and installed in order to meet worst case weather conditions (which in turn would most likely increase the size of your Solar (PV) System and Battery Back-Up System). In other words on very cloudy days your Battery Back-Up System would have to power the majority of your electrical needs because your Solar (PV) System will only produce a limited amount of electricity on these days.
Off Grid Solar (PV) System works as follows:
The photovoltaic (PV) solar modules convert sunlight into direct current (DC) electricity. The (DC) electricity will then flow through a (DC) Disconnect safety device. The (DC) electricity will then flow through a Charge Controller which regulates the charging rate / state of charge for Storage Battery and if the battery is fully charged, the Charge Controller will then bi-pass the battery and send (DC) electricity directly to the Inverter. The Inverter receives the (DC) electrical current from either the Charge Controller or the Storage Battery and converts this (DC) electricity into alternating current (AC) electricity which then feeds the Breaker Panel to be dispersed to the appliances throughout the home/business.
