I have a Classic 150 - which is perfect for 5 strings of 3 panels (285w - 300w) - e.g. use Classic Sizing Tool for your situation. Have had it in operation for 3 months now with DIY Lithimum Ion battery pack and local internet access/control. All is working perfectly and looking forward to adding 2nd one (using follow-me) next year as I expand.

Highly recommend this product.

Also - had returned 4 or 5 times to AltE store and all orders were shipped rapidly and have found AltE to have competitive pricing. Great experience with AltE and appreciate all the video/youtubes they do to help out.
