  • Thank you for the tip on the MUST equipment...I bought two each of a 5 kW low frequency split phase inverter and a 80A solar charge controller. Hooked them up to 8 L16 6V LA batteries, and 4.5 kW of used 250W Canadian Solar panels. System works great! It makes an economical backup system for my utility. Many thanks for your suggestion.

    I'm happy someone else found success with these units. My MUST charge controllers (100A version) and 6kW inverter have been going strong - coming up to three years now without any issues. The one thing I do in Winter is switch to a Victron Multiplus II because the no-load current on the MUST is a bit high compared to the 10W on the Victron - something I have not found an alternative for that comes close...
    I was wondering if your Qty32 280 Amp-hr batteries were commodity-grade or the matched high grade. Based on the price it looks like the commodity-grade. I'm still on the fence about this but plan to order this week.

    The older 280 Amp-hour cells were about $3000 shipped and she is now adding $711 for shipping which is understandable In the current environment. The $1K will buy the off-grid inverter we need.

    Anyway, I sent a message to Amy asking these questions and for a quote. I think there is a 30% discount for the commodity is all related to the time/labor/equipment cost to do the capacity testing/matching. They are still the same cells.

    I don't think you will get the UL certificate for a commodity cell though. EVE in the past distanced themselves from these cells sold through third part vendors...
    Just curious about what you were quoted for your LFP cells from Amy, if it's not outta bounds ;)

    I did not order 280Ah ones from her yet (my 32 I got last year are from a different vendor). I did order 8x105Ah EVE cells from her and they were $512.4 including shipping.

    Not out of bounds at all -- but i can't remember the exact price -- i do know they were at least 1K more though at the time ...
    Hi , I was just looking around for ground mounting ideas and I came across your work . very sound looking .
    In your reply you say that there is no import duty on solar kit in Europe ?
    I was really interested to read that , as I have just ordered a full system ,
    Is there an EU directive about solar eqpt imports that you know of ?

    Where are you in Europe ?

    Continuous discharge current 75 A (1.92 kW) and Maximum discharge current (< 30s) 115 A (3.0 kW). My guess is you're going over those (you have to add inverter losses as well). If you put them in series to get 48V you still have the same current limits.
