I've been looking at the MPT-7210a and it seems nice but I want to run parallel 250 watt panels so I think it will run up against the current limit on a 13s lithium ion power wall.
I saw a YouTube video on the CTK-EV-300:
It seems to be ok but a 300 watt limit.
On eBay it looks like it has a big brother with double the watts and a longer case:http://m.ebay.com/itm/132218486266?_mwBanner=1
I'm a bit concerned that neither has a fan.
I want to run two controllers and four panels for a 1kw array. If that sounds like a good start, I need a 1,500-2,000 watt pure sin wave inverter that won't break the bank and a bunch of 18650s.
Alternative suggestions are welcome but keep in mind I am on a budget.
Thanks.
