I have a 5 battery bank 12V in parallel charged by solar - does it matter which battery in the bank I connect the inverter to
1502227
Connect the positive cable to one end of the battery bank and the negative cable to the other end of the battery bank if possible.It would help distribute the load evenly.

It shouldn't matter, since they are in parallel. I have an eight-battery, parallel setup in which I connected it to the last one in line, because it is the closest to my control panel.

I don't think that it matters. If they are in a line I would hook to th first one.

yes, as long as the inverter is not plugged into ac the solar panel will charge the batteries through the controller. if the ac is plugged in and the inverter starts to charge the controller will no longer supply the batteries with a charge through the solar panels.

Yes,it can as I found my old note books from University and it goes like this. In a 12 volts system-Sine Wave Inverter. 12 volt and 150 amps battery is needed wired in parallel to the Sine Wave Inverter. // means all positive together and all negatives together. The formula is as follows: 10 times the amperes of the battery(150) divided by the Load divided by 2 equals....1500 divided by 70 divided by 2 equals 21 3/7 divided by 2..... 150/7 times1/2 equals 150/14 equals 10 5/7 hours or roughly 11 hours of run time. Further or more alternatively,you will need some tech skills in attaching a Solar Panel to the battery to keep it charge,which is another topic......

No..... and maybe.... The point of using the controller is that with small loads less than the rated amperage, when the battery is fully charged, your load is being supplied with power from the solar (bypassing the battery). This allows the charge controller to float charge the battery and also power your device.... If you are drawing lots of power through an inverter, then yes, you will need to connect directly to the battery.... Just FYI - the unit I got had an UN-replaceable fuse.... I had to create a work around to solve the problem....

i don't remember but it's really simple.the solar panels connect to a charge controller witch connects to the battery.then the inverter red cables connect to the positive post and the black to the negative.if you are useing more than one battery parallel the batteries connect the red cables to positive on one battery and the black to negative on the oter battery and the same with the solar panels.

Hello,If you are charging 12v nominal battery bank you can input up to 400 watts of solar power.If you are charging 24v nominal battery bank you can input up to 800 watts of solar power.The wiring configuration of the 800 watt panel setup must be done so that you do not parallel all of them or not series all of them or else the panels will either go out of the 100 VDC or the 40A rating.The 800 watt setup must be wiring in series/parallel.Please let us now if you have any further questions.Regards,AW

Hi Karen, I think your question is back to front......but I may be wrong. The batteries should be rigged up to supply the inverter with + 12 V Direct Current for the inverter to supply nominal 120 V Alternative Current......The inverter will take power from the batteries and if the batteries themselves are not supplied with power [from solar panels, an alternator or charger] the inverter will eventually take the batteries down to about 10.5 V DC whilst still delivering the nominal 120 V AC. Which is not good for the batteries. I hope this helps.......best wishes....Jack.

They are both good. However batteries are expensive. I only use batteries if I need power. If I want to lower my electric bill I go straight from solar panels to grid tie inverter to outlet receptical. Remember the shorter the distance between panels to inverter will produce more current or watts back through the meter. One more tip make sure your inverter is at least equal to your solar array. 500 watts of solar panels will only put back about 350-375 watts of power.The batteries if run in parallel to create 24 volts will put back about 480 watts. Hope this helps.

An "inverter" should be connected to the battery since that is the source of power. The Renegy system generates power to charge the battery- cables from solar panels to controller & cables from controller to batteries. Separate cables from battery to inverter. This is what I did & it works very well. Hope this helps.

Sure, but you will want to make sure that you have the solar panel hooked up through a contoller/regulator to avoid overcharging the battery. This is true with any battery.

You must use a solar charge controller and absolutely 'not' connecting the solar panel to the battery bank directly. I'm using Xantrex inverter, but there're a few brands work well also. Make sure it's a "true sine" wave inverter, well worth the money. You also want to look into if you want just an inverter or an inverter with charger? The combined unit may save you some time in troubleshooting problems later on. Talk to a few RV installers before making purchase, and avoid the shops who say they'll do whatever you want.

Yes. Each (+ / -) are connected to their own "T-Branch Connector) So each T-Branch will be the dedicated + & - to follow thru to your charger controller. Then to your battery or bank. :-). All in series. 12volt design.

No, the inverter will only invert battery power to 120 Volts AC. You will need a separate charging unit to recharge your batteries.

The solar controller and generated can be connected to the same battery in parallel and not have any problems.I would only see an isolator or disconnect switch necessary if you wanted to remove your batteries and switch them with a different set or configuration.That way you can disconnect your panels while managing your batteries. This is good for preventing your charge controller from getting damaged.Let us know if you need further assistance.Regards,AW

The grid tie hooks directly to solar panels, you do not want to go through a charge controller nor do you want to hook to a battery bank. Using this small inverter I am assuming you have a twelve volt system, make sure you do not exceed the 250 wattage or you will fry the inverter For a little more money you can get a 500 or 600 watt inverter, I have 6 600 watt inverters that have been working great for over a year. I have 3 185 watt panels for a total of 545 watts on each 600 watt inverter, It is best to stay a little under what the inverter can handle

You'll need a charge controller so the connection will be: panels>controller>batteries>inverter

Hello Bart. I will recommend 24v battery bank. For simplicity of wiring, I will also recommend 12v batteries. The 4 solar panels can efficiently charge 4 120AH batteries or 2 200AH batteries. Feel free to ask more questions.rgdsEmmanuel
