Old/new system reworked

Like most here, started small and grew in steps. Along the way I cut many corners. This week was payback time. Reworked everything to meet NEC. Right now I am 99% there.

Things left to do:
Add a exterior battery disconnect to fire fighters.- Do have a 120 amp CB in basement, but still need the outside one.
Signage for disconnect locations for fire fighters.
Ground fault protection- may get a XW-150mppt, so this on hold. Plus I have a split array that are 120' apart with each set of modual frames to separate ground rod.

Review how I got to this point at my webpage:

    Hi Ken!
    Thanks for the post - went to your link and was EXTREMELY impressed at your amazing documentation and detail, thanks for taking the time to share this. Looks like you really put together a nice system there. Are you still using the HF panels? The system I have now is kinda' like your startup - 4 HF panels (amorphous silica) with 2 monocrystalline (PowerUP) panels for a toal of ~110W. It works "OK" for our needs now. But the force is strong to add more!:D

    Thanks for the great post and share!

    Nope, the HF are non UL labeled. Willing to risk them on the shed, $1000 loss, but not the house, $300,000 loss. Sold them on eBay some time ago.

    Thanks for the compliments !

    Hi Ken notice that you are using a MSW inverter to run the fridge.

    Correct me if I am wrong but I thought that one should use TSW on motors if possible and particularly electronics to avoid damaging them.

    Any problems so far with the fridge?

    So far it runs ok, draws an extra .5 amp ac. I am looking at a true sine wave. Maybe in the spring.

    The 600W will run it, but not every time, the softstart causes the thermal on the frig to trip at times.

    Right now in a bind on the system. The days are getting shorter, so put the frig back on the grid. With temps at 50-70 deg. shut down the geothermal system. Now only generating/using 1,200 watts daily compared to 3,000 watts. I know there could be another 300 to 600 watts but how to use it?

    Oh well in another month, I maybe using the battery charger to maintain the batteries. At this time of the year wish I would have done a grid-tied system. But after the first power outage this winter, with me still warm and the lights on, I will be happier than a pig in mud:D
