It's fine to have carpeted floors under electrical panels. It is not fine to have panels, overcurrent equipment etc. on a floor. For a DC system the easy/cheap way to manage overcurrent is use AC service equipment that is cross-rated for DC. Then you can just buy the gear at Home Depot. The first one that comes to mind is Square D "QO" which is DC-...

The NEC is only part of the picture the NEC defines the minimum standards like the breakers being in a panel or box. The 2 places in your house a breaker panel can not be located is in a clothes closet (closet with flammable storage) and a bathroom. Other than that the panel can be just about anyplace Except on a stairway. Your panel can be mounted in the ...

No, not normal at all and you'll want to check the warranty for the panels to see if this is covered. If there is no sign of physical damage then the seal should be intact.

moisture inside PV module No, visible moisture is not normal. PV- panels are sealed and air-tight. But the sealing can suffer from mechanical stress during transport, from wrong handling, from mounting or operation. Every bending, twisting etc. should be avoided. Sometimes the building roof is under stress by setting effects, traffic, earth movings, heat ...

It isn't normal in the sense that it's normal operating procedure. It can be normal in the sense that it does happen as it is hard to keep moisture out over the long term. That is the answer to your specific question and I wonder if you more want to know if you should or need to do something about it or can stop worrying about it. You do need to do ...

Relevant harvest information could be gathered from other PV owners in that specific area. There are many PV forums. If the focus is on own consumption, and if there is no storage and the feed-in tariff is much lower then the feed-out tariff, an optimal configuration is not to adjust all panels to the south, but to have the panels cover a wide angle from (...

It could not only damage the battery. As already mentioned, fast charging of non-defective flooded lead acid batteries with high currents is normally no problem - given the charger meets the lead acid charging regime and all cells and charger are working properly - and the room is vented without discharges from static electricity or sparkings, overheating ...

Those MPPT controllers seem appropriately sized compared to panel capacity. The panels might output slightly more under absolutely ideal conditions, but those are rare. 70A into a 450 amp-hour battery means you would recharge them from zero in 6.5 hours (which you should not ever do, allowing lead-acids to fall anywhere near zero, that is). So your ...
