I have an EasySolar II GX 48/3000/35-32 with 12x 320W nominal solar panels, 8x 12V sealed Lead Acid Deep Cycle batteries and a BMV-700. We are 100% off grid in northern New Zealand.
The inverter component struggles when using power tools (we are building a home off grid) despite a soft start device. I also wonder why a soft start capability is not built in to every solar system?
The system also struggles when the sun is shining and I use excess power to charge my electric vehicle (standard mains charging unit, draws ~1800W continuous). It raises high temperature alarms which (if I don't disconnect the EV charger in time) result in a shutdown. I don't understand why this should be given that the load seems well within the advertised parameters.
So my thought is to add a more powerful 'compatible' inverter to the system that gives us much more reliable power draw- short term for electric motor loads, and also sustained to charge the EV when the sun is shining. As I understand it the RS 48/6000 would be DC coupled (connected to the batteries in parallel with the EasySolar) in this circumstance but would need a data connection back to the GX component of the EasySolar.
I am keen to hear
* whether I am trying to solve the wrong problem, or
* what would make the RS 48/6000 not a great fit to the situation?
