Quattro 48/10000 updated to latest firmware 506
Off grid with generator as sole charging
A situation has developed whereby we have been consistently experiencing on charging that the charge rate starts off as expected at 7kw but every time depletes (whilst still in bulk mode and way before absorption voltage is reached) gradually until it reaches under 1kw and then goes to passthru mode.
We have no ESS activated.
The only way to clear this situation is to restart the VE bus and then it goes back into full charging but then repeats the same cycle, reducing to under 1kw and then goes to passthru.
All settings have been reviewed and tweaked up and down and back and fore but the scenario continues.
Obviously we want the system to maintain the charge rate at the appropriate level and then expect to see the rate fall as it approached absorption, maintain the voltage at absorption and then go to float.
Would any kind person out there have any idea why this fault id apparent?
