Hi I plan to use this to charge a battery that hooked up to an inverter, will having the two connected at the same time cause issues?

It shouldn't cause problems. The inverter would only see the voltage from the charger not the current.

If the two are connected it sounds like you are running a 24V system if that's the case I wouldn't use this one. Other brands make 24V onboard charges.

I charge 2 6v lead-acid batteries (in series) with it for RV - have had no trouble. This link gives the various charge rates and protections. Not sure how the controller would handle 1 bad battery of 3 wired parallel.http://www.directdepot.net/manuals/Go_Power_MAN_GP-PSK_80.pdf

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.

Yes as far I know you can. I have charged both batteries with it and have had no problems.

I can't see why not either. While driving, this gadget and the car's battery are both being charged by the car's system, which has many times the necessary output to run everything all by itself. You wouldn't want to use the inverter when you were charging the battery from the wall charger, but there's no reason to try that in the first place.

Not positive here, but I would be hesitant to use this charger for that purpose and I wouldn't even dream about it if they are in series. (I would dare to believe that they are parallel though.) I would feel okay with 2 standard automotive batteries wired in parallel, but I think you are asking for a short lived charger on anything more than that.

No problem at all. Just connect 2 or more 12v batteries in parallel. I use 4 x 12v batteries.

the inverter will work but you did not say what wattage it is. Are you making the 2 batteries into 12 volts? You will need a charge controller too.

Beware of any connections between two battery packs. Ask someone who is near by and can look at what you are connecting. Fire and danger from fumes are possible.

Yes. Two solar chargers would be needed. Please make sure both batteries are fully charged prior to connection. It is also recommended to disconnect the batteries from any possible draws.

hi I have had good luck with it charging two batteries at the same time for my tracks Slash I think those or 7 volt batteries but I like it it works for me

That will depend on your charger, and not on your battery. However, you should usually charge batteries of the same kind -- not mixed.

My setup is similar. I use an inverter on one side and my generator on the other. When my batteries die then i start my generator and wait like 20 seconds and it transfers. No doubt it'll work!

The short answer is YES, if connected in parallel.... BUT if you are trying to charge a 12V battery system then you will be losing about 70% of the panel power and I highly recommend contacting us to size you into the correct MPPT controller. Obviously you are getting a lot of incorrect or incomplete information. IF you are charging a 48v battery bank then this controller is fine. ML SOLAR

Yes, you can charge the 12 volt battery while the inverter is powering your appliances and electronic devices.

Definitely can use with power inverter, not sure how much you are looking todraw nor the duration, but this should work fine (higher rated batteries willbe abler to handle heavier loads better than lower obviously, so size appropriately).

I would advise against running it in a two batteries to one panel setup. If one battery went bad it could/will cause the loss of the other battery. The charging controller in this unit is meant to work in a one to one relationship to a single battery. Properly wired it could possibly work as a temporary solution. Is it advised? No. Eventually there will be a massive failure when one battery in the circuit has problems and an overcharge hits the remaining good battery. I would suggest a Battery Tender 022-0165-DL-WH. This is a dual battery charger but is not solar powered.
