First, I want to apologize if my referring to products here is considered an "affiliate link." I simply own them and have questions on their use. I'm not endorsing nor suggesting avoidance of their use. : - )
Ok...here goes : - ) I have this 100W solar panel of the roof rack of my Jeep Wrangler https://www.eco-worthy.com/collecti...00w-12v-extremely-flexible-mono-solar-panel-1 Sorry, I only saw the moderator's Youtube video on the ills of flexible solar panels after I bought it!!!
I would like to use it for two purposes. The first is to charge this 10ah battery. https://www.eco-worthy.com/collecti...n-bms-3000-life-cycles?variant=37586593349820
Perhaps TMI: my vehicle's dash camera, which is currently energized by my vehicle's factory batteries (yes, there are two in parallel, long story, part of the Engine Start Stop system to save gasoline at traffic lights) has a parking mode setting that I have configured to shut off the camera at 12.3V, so as to not drain these batteries from successfully cranking the engine. Despite these batteries being hooked to a Deltran 3 amp Battery Tender connected to shore power, on cold nights the camera shuts off because the composite battery voltage of these 2 batteries drops. So I was thinking of powering the camera during parking mode, to the previously linked Lithium Iron Phosphate (LiFePO4) 10amp battery---less susceptible I'm told to voltage drops with temperature..... and charging this battery with the aforementioned solar panel, so I can run my dash camera in parking mode even when I am away from home (where shore power for the plug in Deltran 3 amp charger may not be available.)
With the same 100W solar panel, I thought it would be cool of I could also trickle charge the vehicle's batteries, two AGM's, using this Deltran Brand solar controller: https://www.batterytender.com/Battery-Tender-Solar-Controller .
I like the fact that it has the same technology to charge these AGM batteries differently, depending upon their condition, as does the plug in Deltran controller I have, but this solar controller is limited to 45W panels. Supposedly Deltran promotes battery life with its across product segment charging algorithms.
What is the best way to hook this up? I was thinking about splitting the two leads off the solar panel each into two, one side going to this nothing special PWM charge controller, to charge the dash cam's aforementioned LiFePO4 battery: https://www.eco-worthy.com/collecti...h-paremeter-adjustable?variant=37685431435452 .
And on the other side of the split I'd like to put the aforementioned Deltran solar controller.....but that device can't take in more than 45W as input without frying. Is there something I can put between the solar panel wire split off, and this Deltran product to make sure that the Deltran product doesn't see more than 45Watts?
Maybe I am approaching this all wrong. Maybe there is a better product to stick between the split off of the solar panel wires and my vehicle's battery, like, price notwithstanding, an MPPT controller.
Many thanks for your patience with this newbie! : - )
