February 16, 20197 yr I have just bought VM3 5.2 KW and loader it with 10x250 watt panels , The energy producer by PV is different always with my load (I have not connected any battery bank yet ). Some time its generate 560 watt but when I put more load on it it goes upto 800 watt same time !!! Why its related to my load ?

What sort of battery do you have, and what are the battery related settings? For example, float and absorb (bulk, C.V.) voltages, maximum charge current? Is there an LED indicating the charge stage? Axperts MKS for example have a charge LED that is solid green when in the float stage, and flashing green for bulk or absorb stages. This model still seems to have the premature float bug.

Thank you , I was using it without any battery backup (vm3 can be operated without any battery ),but some one told me to put battery to get beet result ,so I put 4x12 V 160 Ah battery bank and now it started to generate 1.3 KW from PV ,today it was even cloudy ,so hoping good result by tomarrow .

Why its related to my load ? nothing is wrong with your Inverter, if you don't put any load then you won't receive any current from PV, this is how MPPT work. since you have attached batteries, you're getting about 1.3kw because MPPT Controller is charging your batteries, once batteries are charged, then PV will go back to 0Watt which is normal.
