I'm considering this panel to charge a 75ah battery that has a 3.3ah load on it 24hrs/day. Will this panel be enough?

Throwing in my two cents. Get two for this. It'll work fine for awhile for you the way you want to do it, but ultimately, your battery is going to lose charge 'cause you will be running close to max on the panel all things considered unless you are in bright sunlight all the time. Plus, over time, your battery is not going to charge as efficiently. My 100W Grape tests at 5 amps in good sunlight. But then there's nighttime....:-) I run an off grid system, and am going to get a second panel just because of those cloudy days. An MPPT controller will help maximize your charging too. I haven't gotten one of those yet. Throwing in my two cents. Get two for this.

Based on my experience, I think you would need two units. And you would need a maximum power point type of solar battery charger as well. I use two units in parallel to feed a maximum power point type of grid tie inverter and the maximum power that I get, when the sunlight is optimal, is 150 watts. And that is usually less because the sunlight is not always optimal.

I would think a 158ish ah battery would be more appropriate. You never want to take a battery below 50%. There are many factors to consider if this panel is suffient... Where you live, solar aspect, clouds and to get a better calculation, we would need to know the power draw in watts.

Is this a 24volt panel that is not outputting full power? If you hook the panel to the charge controller that is first connected to the battery and you get green light I would go for it.

If your solar setup is designed to charge lead acid battery's wired in series for 24V, then yes. You will need to adapt your charging setup to use the same type of adapter that plugs into the side of the pack.

Yes, but you will need a charge controller with this panel. A charge controller is designed to protect the battery by managing the charge rate.

For a 24V system this would be acceptable. The problem with this controller is with in the loading of it. The out put to a load (lights, inverter, etc.) comes on after there is no light to the panel.

I have two 275 watt panels hooked to mine. I believe I have room to add another. It is a 30 amp charge controller. B

Youre going to need deep cycle batteries as far as output it depends on how manyamp hours the batteries have the solar panel should always charge of 400 watts if tHeres sun look online how to calculate Amp hrs depending on what ur running I can run some fans lights a tv and a fridge in my rv with two batt

I run mine on a 12 volt battery for 20 hours with no issues, I would think the right solar panel would work.

Hey Edwars O. Not sure. What type/sort of system are you putting together? 6V 12V? What are you needing to run, and for how long? What are your energy needs? I can't answer your question my friend without more info. I personally use the 400 watt system with another 100 watt panel. I match my batt bank so every 100 watt of solar for 100Ah of storage. Yes, it is over kill for just myself! I'm still in the learning processes if you will. The panels that come with this kit have zero issues with charging the batteries on cloudy days. I'm very happy with this basic system so far!!

No maybe you should get a 60 Watt sunforce solar panel kit that will work the moultree panel is only a trickle charger not enough amps.

I believe you will need two panels connected in a series for a 24 V system. My panel puts out 18.99 volts max, not enough for a 24 volt battery. hope this helps.

This is an excellent panel. Puts out good voltage with very little light. As a personal rule I have found that one watt solar should equal one A/H battery so the 55ah would be the best choice. Google for"Solar Calculator" but all of these will ask you to define the load before they give you any info.

Dont know if i understand your question. But it doesn't sound like it would work because one 12v panel wont charge 24v battery unless you connect two 12v panels in series.

Yes it will... With the added ports On the panel I charge my phone and this battery so I can charge items at night

Yes, I hooked a 5w trickle charger panel to a 12v battery and it worked well. Might want to go with a 15w panel however- mine loses charge if I leave it on 24/7.

The plug-in charger only puts out 2 amps. If your solar panel USB port has similar output there should not be a problem.

Yes, it should work. You'd honestly be better off getting a second solar panel and wiring them in series to produce 24v.
