Day Five of my cloudy skies solar panel and charging system tests.
I've been running my Comcast provided Internet modem and wireless router off the 300 watt inverter for several hours.
There was about a half volt drop in the battery bank during the first hour, but the charge has held steady since.
Is my one 100 watt solar panel managing to keep up with the power consumption of my modem even under cloudy conditions? Tech manual says the modem has a power draw of about 17 watts.
I went ahead and added a fourth 35ah battery to the bank yesterday, so the primary bank now has a full 140 amp hours of storage. Trying to decide if I should bite the bullet and buy two more to bring the bank's rated capacity up to 210 amp hours.
Remember, this is a hobbyist system for experimentation, but built with the intention of keeping some rudimentary communications available in the event of a long term power outage.
Weather forecast says I can expect sunny skies tomorrow. Can't wait.
