Single Controller with multiple Inverters

[digimart]

Hi,
I already have 2 Inverters ( 1.2KW each, 24 V DC).
Now I am planning to have solar panels and controller installed for charging of batteries and providing current to my circuit.
Is it possible, that I install solar array of 2 KW, and link that to one controller ( 24 V, 40 A ). Onwards from the controller I take out 2 set of wires and connect my two separate inverters and their battery banks.

So my question is that is it possible, and will it work, if I connect 2 identical but separate sets of Inverters and batteries to my one Solar Charge Controller. Please note that the controller me PMW ( not the MPPT one ).

Please advise

That won't work
one array for 1 controller for 1 battery bank works
2arrays for 2 controllers for 2 battery banks work

Short answer - no.

Slightly longer answer - if you connect one charge controller to both batteries, and one battery bank is low and one is high, hundreds of amps will flow through the wires going to the charge controller. This will blow fuses and/or melt wires. If this is really important to you, you can combine both battery banks with the appropriate gauge wire then charge the resulting single battery bank with one charge controller.

thanks all for your guidance.

so as I have understood from your messages, I have 2 options :

1. I setup 2 different arrays, have 2 separate controllers for the 2 separate inverters and battery banks.

2. I discard one inverter, combine its batteries with the other one, and then have 1 array with 1 controller and larger size battery bank


Am I right ?

yes you could set up a single battery bank at 24 or 48V
At that point you could put the 2 24V inverters you have if 24V
or 1 or 2 48V inverters.

sir,
i am little confused with your reply.

let me again narrate my present items:
I have two (2) Inverters of 24V each , ( 1.2KW each ) in hand, and have four (4) batteries of 12V each.
At the moment I have hooked two batteries with one inverter.

Now i plan to install solar panels, and also solar charge controller.

Please advise least cost way to achieve the target and use maximum of the available hardware in hand.

Make one large 24V battery bank with your batteries
Connect all of the solar to this bank through a charge controller You can split your array and have two charge controllers feeding the one battery bank if necessary otherwise you will need a charge controller big enough for the entire array.
You can then connect the two inverters to the single battery bank.

thanks , now its so very clear to me

i appreciate your time and effort to clarify my query.

thanks again

Just a thought, why do you need to run 2x1.2 kw inverters? Do you have that much load? Im assuming you are planning on powering up high load appliances using the inverters in parallel. Some inverters can be connected in parallel but most inverters cannot. 2 or more inverters can be connected to a single battery bank just as all the others said. Check the specs on the inverters if they can be run in parallel, otherwise you have to have different circuits for each inverter and their loads. If my assumption is wrong, disregard the post.
