I have a Phoenix inverter 12 250 connected to the load output of my mppt 75/15.
it works great when I test a simple device but when I connect it to the house power to have energy floating into the house the led turns permanent red.
What am I missing?
Should I connect it to the battery directly instead of the load Output?
Did I miss match the Phase because I use a schucko connector for injecting into the house?
Or did is the 12 250v just not the right device aka too small? Sine I only use 2 x200 watt panels I thought this would be a great match.
thank you all in advance for any hints
