If I had 3 of the ePVL-144 with a battery bank of 4 100 amp 12 volt agm batteries, what would be the recommended charge controller and inverter?

One will need MPPT charge controller with this setup 45 Amp should be good enough for three of these solar panels. Morningstar is the brand we sell & support with these panels.

Each 24 volt ePVL-144 supplies a maximum amperage of (144watt / 24v = 6 amps) to the charge controller. Three of them wired in parrallel ( with proper blocking diodes) will produce a maximum amperage of 18 amps (3 x 6 amps = 18 amps) input into the charge controller Assuming you wire your batteries in a 2 x 2 bank for 24v @ 200 amp-hour capacity, you will need a 24volt charge controller capable of handling a minimum of 20 amps input. You may want to get a 30 amp controller for a little extra amperage headroom for safety. Your inverter needs to accept 24v input and have enough wattage on each outlet to power you desired equipment. Your battery bank has a maximum power output of ((24v x 100 amp) x 2 banks)= 4800 watts for one hour. It is not recommended to fully discharge the batteries or to run the battery bank at maximum amp capacity (200 amp hours in your case). AGMs should be discharged no more than 80% of thier rated power (100 amp-hour x 0.80 = 80 amp-hour). In your arrangement this reduces your useable wattage to ( 4800 watt-hours x 0.80 = 3840 watt-hours). I would say a 5000 watt inverter would safely handle you battery capabilities. The inverter needs to accept 24volt DC input and should be a true or 'pure' sine wave variety if you will be powering sensitive equipment like computers. You could use several smaller wattage inverters in a stacked configuration if you do not have the funds for the larger inverter. For example you could start with a 1000 watt inverter and add up to 4 more as your budget permits. Be sure to buy stackable inverters if going this route.

I have a Renogy 40 a controller with three of these batteries in parallel and the system works great! The VMax website provides all the details you need on their batteries. Just remember that when hooking up the charge controller to hook up the positive at one end of the string of batteries (in parallel), and the negative at the other end.

What four wires? I have a six battery bank connected in paralel (positive with positive, negative with negative) and in the same way to thepower inverter. do the same with the charge controller in the other extrem of the battery bank

I personally would use the Save A Battery 2365-36 36-Volt Battery Charger and Maintainer.

You need a charger that has a setting for AGM batteries. My charger has settings for 3 types of batteries, standard flooded, AGM and gel. Optima recommends a 10 amp charger.

These inverters are commonly used with multiple 12 v. batteries. They need to be wired in parallel --pos to pos, neg to neg. This creates a "bigger" 12 v. battery, but the voltage at the terminals is still approx. 12 volts. With this configuration multiple batteries will charge at the same time. ALWAYS use identical batteries of the same age/capacity as one bad battery spoils the bunch.

If you are hooking this up by itself you'll only want a charge controller to prevent the battery from overcharging. If you are using this to hook up an ac plug in battery charger, then you need the inverter for the charger.

If the generator has clean output I see no reason that the BatteryMinder AGM could fail to charge a big AGM battery. A cleaner solution might be to charge the bank direct from the solar cells, as long as the solar array doesn't have enough power to overcharge the AGM bank.

I use it to charge and keep the charge on a 12 volt 7AH battery and it works fine. No need for a charge controller because the amps it puts out are very low, so you should be just fine.

You need to keep your voltage all the same, you can use this controller with a 24 volt panel but you need to have your batteries wired at 24 volts and if your using an inverter it needs to support 24 volts.

Hello Jennifer, Yes, the Guardian 12V Charge Controller will charge any 12V battery. The Guardian can handle a maximum of 90 Watts input. You can use 3 - 4 Boulder 30 panels with the Guardian to charge your 12v battery. Thank you for your interest - I hope we can help you - Denis, PrepareDirect

We do not recommend connecting the inverter directly to the charge controller; connect it to the battery instead. 8 AWG be sufficient.

for my 36 volt system I bought 3 12 volt (15 amp hour) rechargeable batteries and wired them in series and hooked them to the controller with a connector i got from a model car store. hope this helps

Your charge controller needs to be able to handle 48v input...Morningstar TriStar can, and the Renogy PWM 30 Amp w/LCD can also. Check out pvdepot.com and batterystuff.com-- both have good info for sizing your system correctly.

Most any good charger will work. Check to see if it has a special setting for AGM batteries. If so use it.

Gene,We have a couple of inverters that would work. Are you going to set your system up as a 12 volt or 24 volt system.Joe

You'll need a controller, I'd buy the deltran brand instead as they are more stable and have the built in micro chip that won't overcharge and fry your batteries.
