Bruce K got a reaction from root in Pylontech Internal Error and High Voltage AlarmsThanks @root, interesting reading. I have all three systems set to Victron's recommended charge voltages which are much lower than the Pylontech specs. Two of them include PV and the third is backup only. In all cases, the problems started a year or two after installation but it could still be a cell balancing issue. I'll try what is suggested. Thanks for the links.

Since posting this post, I've spoken to the client and he confirms that his prepaid meter is registering usage even though his PV production is well above the current load. So I'm fairly sure the firmware is allowing grid feed-in as mentioned in another post that I saw.
South African prepaid meters are dual core, not quad core, so cannot determine direction of energy flow and therefore charge the consumer for feed-in energy. I will flash the newer firmware tomorrow and let's see what happens.
