Will it be 350 Watt OR 1400 Watts? In your suggested scheme, there are two power converters in the path from Solar panels to the batteries, whereas in the other model that you mentioned, one power converter, i.e. In both the cases the full charging period will be about 16 hrs. i have 20 nos. Following are the steps involved in the installation process: Step-1: Mount Installation. 1. Will battery charge if we connect battery directly with solar panel without chage control device? so if 380 instead of 220, then current will be slightly decreased .
Because if you increase Voltage, then current decreases ( → P = VI )
So Keep in Mind Load only. source? DO IT YOUR WAY SOLAR SOLAR PANEL GUIDE ... our Solar Permitting Guide. Hope you will clarify them too. If each panel is of the same rating please inform accordingly.Then only we will be able to advise you in this regards. In this case, the total required current (20 A for Batteries Charging and 10 A for directly connected load). 4. Engineering site visit: the first step to getting your solar system installed. 5.6 A Hence the max.backup you can achieve would be 5.6 hrs.if your battery is fully charged.
