Currently the LoriBell has a single solar panel supplying its’ power needs.
RENOGY 50W Watts 50 Watt Poly Solar Panel
Th positive side of the panel goes to a Sunforce 10amp Controller.
And then the Negative side of the panel runs through a Watts up meter on its way to the controller.
WattsUp meter left, controller to the right in the above photo.
I have the controller output wired to the always hot side (with an inline fuse) of the battery selector switch. I keep both of my battery banks in on position when we are away from the boat so they are both constantly being charged or floated. I keep the mains on the bottom of the DC panels off.
This results in all 3 or our batteries (2 house in bank 1 and 1 starter battery in bank 2) also supplying the bilge pump that is hard wired to the start battery.
By wiring the -dc from the panel thru the neg side of the meter I can look at amps hours generated, current and total.
The panel currently sits on the top of the house.Plans are to install it much the same way as we have the 15watt panel on the Clew. We currently are running 2 house batteries totaling around 210ah or so. We run our FM radio, charge our cell phones, 2 vhf hand held radios, run a fan, led interior lights, fresh water pressure pump and the solar panel has been able to keep pace.
I do want to get a better grade of controller and possibly another 50watt panel for extended cruising.
The reason for a better controller is due to the WattsUp meter. It shows the max we have yet to see is 33watts out of our 50watt panel. A true Mppt controller has less loss than the low end Sunforce, we should be able to get over 40watts out of our panel, better utilizing the space used by the panel.
