Did build a wood base to stack batteries on just in case an unlikley flood happens, but racks stack well, easy to do. Did learn that when batteries are linked, only the master shows LEDs indicating total charge. Using existing Classic 150s, got help from Midnite Solar regarding settings and options (they have some tech PDFs available). Much improvement over old batteries, so very happy.

    These are the perfect cable management solution
    These were delayed in shipping, but worth the wait. If you are using Iron Ridge rack system, get these too.

    The inverter works great for my use. SMA's app is a bit glitchy. The overall price and shipping options by StellaVolta are the best out there. It was shipped quick.

    IronRidge is the king.
    I use IronRidge brand for my solar system projects. every product is has a gold standard. i love both Tbolts and Square bolts. Square bolt bonding hardware seems lot more strong vs tbolts save little bit time. i highly recommend IronRidge hardware for solar project.

    I believe I will like the product when functional. Notified Stellavolta online immediately upon opening. No action or guidance from company regarding the next step. Customer Service seems to be nonexistent.

    This thing is heavy

This is all good because it means there is a honking large transformer in it that is good for high demands and heavy loads. It's going to be overkill for my use but I'll know that if I ever need to tax it a bit it'll laugh it off I haven't got it up and running yet, so can't comment on that. But based on what I see, this looks like a quality unit that will serve me well

    Great experience.
    Wonderful. Full order shipped quickly. The site showed in stock and it was true. Only suggestion is to bail on USPS until they get better. My order was split between freight and USPS. Freight was 2 days, USPS over a week. Strap the smaller bits to the freight. Hats off SEFL.
