I have recently brought a solar kit. With a victon 175w panel and a victron mppt 75/15. Once installing it has worked for around 5 days. The last couple of days it produced nothing. Even though good sunny days
When looking into today I found the solar panel at 19v when testing disconnected from mppt. When introducing mppt it drops to around 13v. This causes the batteries not to charge.
Has the mppt failed?
