This is a relatively new and small system that has previously worked as expected. Has been disconnected past two months. Was reconnected yesterday. The two SBP's were updated. One SBP is 'charge' and other is 'load'. The VE Li-ion battery was charged to full via solar and orion Tr smart as of today. There was no DC load output from the 'load' SBP. On the smartphone I could not toggle this SBP to "active", it did display consistent battery volts. Voltage checked with 13.35 on the 'IN' and 2.64 on the 'OUT'. I could not reboot unit from default/power off. The 7 digit display does go thru a flashing mode with 'zero' above and below, (not a full digit or letter) briefly, then no further blue indicators.
I'm curious what I did to toast it. I feel confident that directional wiring is correct. Have ordered a replacement.
