    12KW Growatt increasing size of my PV array and need advice please.

    As I've said before the cheapest thing for you to do is for You to purchase another 6 string combiner box so you can split your array up into two strings 1 for each pv input on your 12kw Growatt inverter. 1 combiner box would have 2 panels in series and 5 strings going to it and the other...

    12KW Growatt increasing size of my PV array and need advice please.

    With a quick glance you can see for instance that at 0*C you should assume 110% of your arrays rated open circuit voltage, and at -25*C you should assume 120% of your arrays rated Voc.

    12KW Growatt increasing size of my PV array and need advice please.

    I'm getting 25 to 30 KW of solar a day pretty regularly now with my 6.2 kw's of solar panels. So hopefully I will see 50 kw and above pretty regular after I get the other 8 kw of panels installed.

    12KW Growatt increasing size of my PV array and need advice please.

    Yea I don't see the 6000 watts very often it normally peaks at 5000 to 5500 watts for a brief time during the day if I have no clouds and my 600 ah battery needs a good bit of charging and I have a decent load on the inverter. Adding this new array should give me a possibility of up to 14,000...

    The combiner box gives a good place to tie all of the strings into one place with a breaker on each string and then leave with only 1 run from the combiner box at the pv array to the inside pv breaker before going into the inverter pv input.

    On the Growatt if you have the Wifi dongle plugged into the USB port on the bottom of the Growatt inverter, the dongle covers the printer port where the cable plugs into from the raspberry pie with the Solar Assistant software. So I use a USB ext. cable to plug 1 end into the USB port on the...

    Here's a little extra information for our Growatt users that I thought some of you may be happy to hear, I have figured out that if you want to see both the shine Wifi app on your phone or computer along with the solar assistant app for your phone or computer, all you have to do is get a Usb...
