Because you have mixed the 360w and the 335w, you need to use the lesser one when doing your calculations. i.e 12 x 335w which gives you 4020w total at 100% efficiency. now, check the spec of your panels to see their efficiency and deduct that from your total. Assuming that they are 80% efficient, you get 3216w as your total. Now, factor the other stuff like tilt angle and azimuth etc 

This is just a rough estimation 

I wish panels were 80% efficient.

Key word is ''Assuming''

Any more reviews from Growatt users out there? 

We bought one in March this year, stop working 3 months later,supplier need 21 days to see if is under warranty

The Growatt online seems to have its own LifePO4 lithium batteries, but from my research you can use it with Pylontech or other Lithium batteries but for system parameters you may have to use “User” for battery type and I’m not sure how receptive the Growatt is to the BMS of other battery types, other than its own.

If you can find some contacts in the Aussie market, it may help.

Hi it works well but trying to get the Growatt (I use a SPF5000TL HVM-P) to communicate with a Lithium battery  management system is a dog - I get no comms try what I may. Setting battery type to user def and filling in all the battery settings does get it on the go, but Growatt cannot read battery levels without a BMS comms and Growat will merrily go on its way ignoring the settings until the battery dies which can be a pain as you  can't restart the growatt if it does not see grid and battery, leaving you with a dead battery and the only way to get the battery living again is to use a standalone mppt pv charger to revive it again.

What lithium batteries do you have? Polytech, shoto ect
