We've had two M250 failures, out of a couple thousand. Both failed
in the first few weeks of operation. Our M215 experience is
similar. <br>
<br>
Still doing M190 replacements just about every week, and a few
whole-site swaps.<br>

Are you having a different experience?</div>

How is the Gen4 Enphase (M250) holding up in the field? Any
marked improvement over M215 in terms of failures?<br>
