How much real charge would this give a depleated deep cycle 12 volt battery in 6 hours of direct florida summer sun?

My solar boat lift has been installed for 2 weeks, therefore my experience is recent. In direct sun (southern facing at 26 degrees) about 4 to 5 hours, if all other factors are working well.

Any 12-volt deep cycle will do but don't get one of those skinny ones. The ones you want are roughly the size of a car battery. I'll try to check the brand of mine and update this, it's worked for 4-5 weekends a year for almost 10 years now

Well yea, use a battery charger , or a deep cycle charger with a max of 35 amp .Most deep cycle batteries use a slow charge rate anyway which is a lower amp charger.Just keep the amp below 30 to 35 amp @ 12 volt. This is not a 24 or more system charger.

Approximately 6 hours in direct, full sunlight. Try to keep the panels at the proper angle by adjusting panels in relationship to the sun for maximum charging of the battery.

Yes 8 or less but if you charge it up at home already then the sun will keep it charged for days as your using it.so be ready have it already charged before you use it. Them the sun will keep it charged for many days.

Yes it will overcharge your battery without a charge controller. I used a Sunforce 7 Amp Charge Controller which is $13.99 on Amazon. A diode won't work.

At 200 W it puts out 12 V DC charging for deep cycle batteries. You can expect anywhere from 7-11 amps at peak power generation. You can also use it in 24 V mode, and expect half the current to the batteries. It will keep your batteries topped up. You can then use the batteries like you normally would, whether they power an inverter to power 110 appliances, or just 12 volt accessories. You can expect about 1 k-W-hr from these panels, with the 5 hour approximation rule. Should be enough power to recharge a 125 ah deep cycle battery, assuming a 50% discharge.

I don't know because I used 3 12v deep cycle batteries with a 55W solar panel charging them. The pump runs off the batteries.

Ryan,,al I can say is I have it hooked to a 12 volt marine battery and cant tell that it has done me any good at all..had plenty of sunny days and still dont seem to do anything ,for me anyway...

I use a Battery Tender Junior, 750mA , takes about 6-8 hours to put a charge on the 12V 7AH battery. Time = amp hours / amps. Most likely takes less time than calculated because the battery carries residual charge. Your scenario, 500 mA, should take a little longer.

That is going to depend on how discharged the batteries get each night. To give you an idea of what to expect, I have a 1600 ah battery bank and 6 panels. They are able to fully charge the batteries each day as long as it is sunny. They produce around 30 amps for about 5 hours mid day in February. With 2 panels I would expect 10 amps. I am in northern Nevada, farther south you should get more sun/power.

It appears to be designed for a single 12V lead-acid battery. Will typically provide between 3A-4.5A charging current on a moderately sunny day.

You should be able to use this battery just like any other deep cycle battery. It will work on an inverter, actually it will work better than most other batteries because of the dry cell.It wont give out as fast. I charge mine with a solar array, and by now I have cycled it over 300 times, and it is still going.

Remember that you are pushing amps back into the battery, and with normal losses this 5.3A panel and charger will likely give you 4.5 amps per hour at the battery in good to excellent lighting conditions (that's what I'm getting here in central Indiana). In a day, consider that you'll have 6 hours of bright sunlight, and another 4-6 of indirect sunlight. Conservatively that's about 8 hours of (8 hours x 5 amps) or 36 to 40 Amp-hours restored. That's enough to restore your 85 Ah battery each day if you take it down to 60%. This system should be fine for your battery--and others might point out I'm being very conservative. Even in late afternoon in indirect light I'm getting 4+ amps. You may find a fully-recharged battery each day by mid-afternoon.

You are more likely to over charge the battery with a 12 volt unit. Just ensure the whole solar array is in the sunlight for optimal charging.

I am using a 10w on my deep cycle battery on my boat. It keeps it fully charged after a few day of sitting in the driveway.

If I had it to do all over again I would probably buy something better. Batt is probably 1600 and the solar panel puts out 1.5 watts per hour. Took 2 weeks for solar panel to charge internal batt in the window sill, direct sunlight in summertime.
