eSmart3 MPPT and panels in paralell

[colonel]

I have 12 battery, 6x100w panels and Chinese MPPT called eSmart3.
It has some problems or features and I'm looking into other options of MPPTs.

1. Panels are 18V. When all in parallel it cannot track power point at all and constantly resets. According to seller it happens because 18v is too low for MPPT mode. I'd assume it should switch into PWM mode but it doesn't. So I connected it in 2s3p.

2. Every morning it needs a reset by disconnecting a solar wire and connecting it back. Otherwise it will generate only 25w till noon. Some days it generates 25w all day long until a reset. After the reset it immediately starts generating proper wattage (ex. 200w).

I never had any other MPPTs so I'm not sure are those above bugs or features?
For example if I get EPever MPPT will it solve all those problems?
