Wrenches We have been doing testing on the Blue Ion over the last several months, we have been using PV, back up grid connected charger, we have CT's on DC in, PV in, Charger in, and Load out, some days we push to three cycles a day, other days 1/2 cycle. The Blue Ion BMU has done well keeping everything in control including a relay for the charger. Eguage has done all the monitoring and has some impressive data. Jerry
