The direct load can be directly powered up through solar power and a charge controller during the sunshine day time and during the shading night the dc load can be powered up using the battery.

Using solar panels to charge leisure batteries.

My plan is to use a 400w inverter attached to the battery at night then use the solar panel to trickle charge the battery at night. A complete note on solar panel installation with calculation examples the dc load light fan etc is directly connected to the charge controller and can be fed up by two power sources. The bulk phase first stage the bulk phase is primarily the initial stage of charging a battery using solar energy. Solar array the solar array is the panel or set of panels.

Dual battery bank having two independent batteries or sets of batteries performing different functions. The additional 10 is to make sure that the battery is fully charged. An example of this would be a start battery and an rv s house battery bank. Solar charge controller keeps the solar panel from over charging your battery or batteries.

I just bought a coleman 6w solar battery charger. Then take the battery capacity which measured in ah and divide it by the amp rating the result from prior computation of the solar panel and then adding 10 of the charging time to it. Using this example you can see that it will take at least 100 watts of solar power to recharge a 100 amp hour battery in a few days. To charge a battery with a solar panel connect a charge connector to the solar panel.

Then run wires from the battery to the charge connector making sure to match the positive and negative poles. Assume you take a discharged 100 amp hour battery and charge it with a 30 watt solar panel under ideal summertime light conditions. Generally a fully discharged 12 volt 100ah battery needs 1200 watts of energy to be 100 recharged. After a full week the battery will be just about fully charged.

The bulk phase will initiate when the battery reaches a low charge stage and that is usually when the charge is below 80. Most likely a car battery possibly a marine gel battery. To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below. Divide the wattage of the solar panel by the voltage of the battery to get the number of amps your charge connector needs to handle.

Charge time battery capacity ah ampere rating of solar panel 10 of ct.
