I am leaving home and the solar system will not be used for few weeks. My system have FLA batteries. I wonder if something needs to be done in this case like disconnecting the fuses from the solar panels or batteries. I'm just planning to turn off the inverter, is that enough?

I have hybrid inverter with charging settings for AGM and FLA batteries. I'm wondering what is differences between these two settings? Also can you damage batteries if you charge with wrong setting?

In my combiner box is some kind of electronic circuit board. On board are connected all positive (+) wires from PV so I suppose that is some kind of busbar. Behind board is heat sink. Has anyone know exactly purpose of board and how it works?

My hybrid inverter is showing 27V from PV input during night. There is no amps and watts. I measure inputs on combiner box and there is 0V. Does anyone have a clue?

I have problems with short cables, so is it important to connect the solar panels (two in series) as in drawing no. 1 or they can be connected as in drawing no. 2?

I have a hybrid inverter with two acid batteries (260a) hocked up with 6 x 285w panels. In house I have separated electrical wires; one parallel for grid electric and one parallel for solar electric. Both on 220v. When there is sun I can run everything on solar power without using grid energy...

Will a cable thickness of 10 mm2 (8 awg) be sufficient to connect the panel (combination box) and the inverter at a distance of 10 meters? I have 8 285 watt panels, connected in 4 series giving 38 amps and 78 volts. The inverter is 24v.

Hi, I have hybrid inverter with no DC output. Inverter is 24V, connected on two 12V batteries. Is there way to make 12V DC output somewhere in system?

I notice that in some combiner boxs surge protection device is wired positive to negative and negative to positive. Why? What is correct positive to positive or positive to negative? And is that important?
