Hey,
I have 11 modules of Sharp NA-E120G5 and each produces 44.9vdc maximum
but 44.9vdc are insufficient for 2 pairs of 12vdc batteries connected in series i.e 48vdc.
what should i do to make them usable for my home use,please
also explain if can i use them with/without batteries and how?

1)Some one told me that i have to put a pcm6040(Taiwan) controller followed by the ups(with backup) with these solar modules to make 44.9vdc able to charge a 24vdc/48vdc system,then ups/inverter will supply 220VAC (required) for the house load.
Also he told me that this is the only way to make them usable for (1-phase 220vac) my house load.

2)If i make two groups of 10 modules that are connected in parallel fashion to each other while each group contains 5 modules connected in series making 44.9vdc X 5 =224.5vdc and 125w X 10 =1250w. Next are two options in my mind:
a) Make 224.5vdc to 220vac , to load(without batteries). (I don't know if it is possible or not and if possible please tell me detail.)
b) Make 224.5vdc to 12/24vdc ,then to batteries to inverter / UPS to load.do i need any controller for this?

Please tell me if some one has a better solution.
Thanks.

Three models that accept 150 volts input up to 200 volts on one model and others not linked to, which take up to 600 volt solar array inputs.

 

Thanks KERMIT2 for your reply!

What if i use Voltronic Axpert MKS 2K-@$plus model hybrib inverter.

5 pairs paralleled each other each contains two 2 modules in series making 2x44.9=89.8v
While its MPPT Range @ Operating Voltage is 30vdc-115vdc.

 

Its actually,
What if i use Voltronic Axpert MKS 2K-24plus model hybrib inverter.
