A new site with CCGX, Multiplus-II 48/5000, MPPT 250/100 and self managed lithium battery. The Multiplus wont turn on unless the CCGX is first unplugged. The CCGX can then be plugged in and the system works as expected (System is on VRM) until the Multi is turned off, then the CCGX needs to be unplugged again to power up.
Look forward to thoughts
