Works great right out of the box. Communicates perfectly with my 4 Mega 314 batteries. Still looking for inverter for system.

Works as intended. Enough power cord for most use purposes with the battery leads that came with, probably about 8 feet or more length.
Only complaint and it is more of my issue. The power cord and battery leads is on the wrong side for my current use case.

Everything works as explained. Already used a few times!

This charger is solid and looks much better than the previous 60a version. It has all the functions and adjustments to charging my 8 server rack batteries, it works great I love it

My 13k Generator would not run steady enough to start the charging process on my solar inverter. fault was Hz were not stable. I purchased this EC100 charger, It charges like a mad man. The only problem I have now is the Generator won't put out 100A. Its a great purchase and works great too.

So far going really well with running at 100amps. I have it running off a 25k generator at 240VAC. It was easy to set up. Have running off my buss bar to 24 batteries at 2400ah.
B
the unit has so far been plug and play. soft start is an amazing feature to have. i have only about a 5,000 watt generator (the smallest you could/cheapest i could find that could do 240v and the 100amp output is the sweet spot to use the gen to its compacity
only used it 3 times as of now so long term still in question, but i need it to supplement my solar for poor winter positioning and cloud cover
W
This new 100 amp charger is an awesome addition for charging my lithium ion batteries for my solar power system. I live in the northeast, and sunshine is hard to come by due to the winter season. This unit handles the portable generator input. I purchased the charger when the pre-sale was active. A great deal. I like this charger much better than the more expensive charger from 3g4. When I adjust the amperage setting the unit just ramps up or down without hesitation. The other unit when adjusted will stop and reset and slowly start back up. Highly recommend this charger for anyone that is interested.

Work wonderful
