I have your DROK Digital Programmable Time Clock Switch Timer Relay Board DC 5-60V. It is connected to 24VDC (two 12vdc parallel) batteries. I keep the batteries charged with two 12VDC trickle chargers plugged into 120VAC.
Lightning storms always reset the clock to 0000. At least I think it resets to that. The clock is always hours off after a lighting storm. The power connection is to DC batteries, the storm should not affect the clock.
Any suggestions?
Thank you.
