water purification for home in philippines?

We Answered:

kamusta? have your water sample check by a lab first, then decide on what purification system needed. Who knows you might not need those power consuming apparatus.
If you do need one, i can refer you a water mineral pot (water purifier -gravity type -and making it alkaline for good health)

Need advice from an electrician?

Last first - the panels are only putting out 12 (or 24) volts to charge the batteries, so there is no safety factor in grounding the frame.
To answer your main question completely would require knowing the circuit. It seems like the inverter might have a ground connection through it. The inverter I had in my school bus camper had outlet mounted on it, so there was no consideration of extending the circuits. I think you have got to get the manufacturer to tell you otherwise there is a risk of high voltage in the wrong places. I would think the DC ground should be separate from the panel/neutral/safety ground.
