    Inverter recommendations for 48V off-grid installation

    Have you decided on any inverter? I am looking for a good one too and I think warranty should be an important factor. I think MPP is only 1 or 2 year warranty - so not too good. Not sure about other inverters proposed here.

The branch which is feeding 120V load will have a small current on neutral that can make the overall potential of the branch to decrease - not sure if I explain it well but I feel the 240V...

    48V or 51V battery

    I see batteries with 48 and with 51V - they are very close only 3 V difference. Which one should I choose? What dictates what voltage to be used? Is 48V made out of 15 cells and the 51 of 16 cells @ 3.2V? What good company you recommend for a power wall 5KW - being it 48 or 51V?

    affordable ground mount system for 30 panels / 450W

    Solar ground racking system with seasonal adjustment - 30panels

    Hi, Anyone can recommend a reasonable priced ground racking system for 30 large panels? Does tilt adjusting really make a good difference in overall solar power you get? Do I really need this feature or a fix system is OK. Thanks
