This will support and fully charge ? amp hr batteries, assuming no drain during sun hrs? I am getting lost in my assumptive calculations.

If your have 5 peak sun hours, your battery 166AH can be fully charged within a day.

I have 4 panels and I was getting this the other day. 283 watts at 20.7 AMP

50 watts from this unit is assuming a bright sunny day. However, a 12V / 9Amp Hour battery should be able to fully charge during the day....This will give you 3-4 hours running your 3x10 watt lamps during the night. Make sure you connect your battery to the Solar Panel via a charge regulator.

Yes, You should put a charge controller in line to batteries, rated at the proper amps/watts so you don't overcharge batt.

Yes, But that depends on how much you are drawing them down. If it is to just keep them charged up (trickle charge) definitely yes. For an example if you are drawing 5 amps per hr. for 10 hrs your batteries would need to be rated together at 50 amp/hr. Your charger and panel would be able to keep up to this But the sun doesn't shine every day so you could start to run out charge. and the batteries will drain down. The six months in summer it would be able to maintain the batteries. You just have to be able to put back into the batteries what you have taken out of them.

Yes. Fully charged, the battery box holds a 60 amp-hour charge @ 12VDC or 6 amp-hour @ 120VAC. If your amplifiers consume 250W @ 120VAC, thats a little over 2 amps x 2 = 4 amps x 12 minutes = 48 amp-minutes or 0.8 amp-hour. Theoretically your amplifiers will work for 7.5 hours. Realistically, something less than 7.5 hours, because of line loss, resistive heating, battery age, etc.

I am testing this. And from my last 2 times of charging 2 AAA's. i gotten the charge by using Solar and USB with a RavPower 15watt solar panel. down to about 30-1hour vs 3hours of just the solar charger on the XTG charger itself. I'll message back when i test out 4AA's with this try. But it seems pretty good chaining the integrated Solar panel with a USB high power Solar panel together.

You'll be charging from the battery pack not the panel it self. It goes sun panel battery then device. So it will be a continuous charge until those barriers are depleted. And they just recharge from the panels

Yes it will work. It's a higher rating for discharge of current(milli-amps) per hour. The battery is designed to be drained faster and stand up to heavier duty loads.

Sure. It is more so a battery maintainer. It will however charge a battery, but several days and lots of sun needed.

If you use a battery tender to maintain your batteries when not in use, then I would imagine you have the pig tail attached. Just plug into the pig tail. However if you are not charging the big battery in some way it will draw it down. My opinion, if you camp a lot, invest in a good quality solar charger.

the output is wattage and its 5 watts- while I would never say never it is highly unlikely you will overcharge a battery with it- it does not put out enough amps (260mA) to sustain high rate of charge- I keep it on my motorcycle battery thru the winter only charges when in direct sunlight and the more the better

Yes,, just be sure you have them hooked up correctly.. I have 2 -12 volt deep cycle batteries and 2 6 volt good cart batteries hooked up to my panels via the controller. The Sun force charger drew moisture and burned out. I replaced it with a Thunderbolt controller. It has a digital readout which is far superior to the simple/confusing light system on the Sun force controller. Also it was only $30-$5 shipping and I received it in 2 days.

Charging time will depend on several factors... how sunny it is, how much capacity (rated in Amp Hours) your battery has, etc. The R15-300 produces 0.3A (at 15V) to charge a 12V battery. For example... If your battery capacity is 10AHr (amp-hours) and it's down to 70% full, that means you need to add 3 AHr back in... As this panel produces 0.3A, that means in 10 hours of full sunlight (max sun) you will restore the depleted 3Ahr. Of course, the sun intensity isn't always at max strength, so it would actually take longer than that. If you need to recharge faster, then a larger panel will be needed. I hope this helps explain it. Pat

I've seen some discussions where there was a regulator required for use with solar chargers in some situations. Had the same issue with my lawn tractor; no charge after 8 hours in the sun. But it works fine for other batteries... go figure. May want to ask someone at your cycle shop about how to use this. And the other responders are right, if your battery is stone dead this thing isn't gonna help you. I found a 6A Stanley charger at Lowe's for $25 to use on the lawn tractor.

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.

I've seen this question before and found one particular answer/response very helpful- the charging system of the vehicle you are putting it in used to charge a lead acid battery did it not? I use a solar NOCO trickle charger on mine. NOCO Battery Life BLSOLAR5 5 Watt Solar Battery Charger and Maintainer

I take it that you're referring to AA rechargeable batteries. I have Sunlabz 2600mAH double A batteries and it does a good job charging them. Hope this helps.
