May 26, 20233 yr I have a 6yo Axpert MKS 5kva 48v charge controller/inverter. I recently had the motherboard replaced. I hook up a generator to top up the power on rainy Western Cape days. Prior to the MB replacement, the Axpert would see the genny and charge the battery, along with whatever solar was available. Now when I start the genny, the controller operates as I’m used to for about 3-5 minutes, then, even though it registers AC coming in, it no longer shows the expected display or charges the system. Here are the current settings for the device. Can anyone help?
