Installation
Get ready the related tools&cables.We suggest you choose the appropriate cables tp ensure the current density<4mm² and this is good for ducing cable voltage trop.Recommendation:30A using 10mm² cable.
1.Check whether installation place accords with the relative safety rules.Please avoid installing and using the controlling under the relative safety rules.Please avoid controller under the following conditions:Wet .dusty places or places with flammable and explosive gases.
2.Install the controller at the vertical plan.Please refer to chapter 5 for more detailed info about the spacing between the installing holes.In order to make the spacing between the installing holes.In order to make the controller have good thermal disspation,please spare 10cm above&below the controller.
3.As shown as the right figue,connect the loads,battery and solar panels with the controller in order.Pay attention to connect the loads,battery and solar panels right.
4.Plug the external thermal sensor into the interface of the thermal-sensor on the left of the controller
