Ok so semi flex chinese panels are a poor investment, wish I knew that before i wasted 400 euros on them. Live and learn I guess. I will be posting test results next week, just in case some poor soul finds it helpful in the future. Thank you guys, downwinds and fair seas to all

My friend, just the fact that I am not the only one there makes me a lot happier. I was going crazy over this. We do a lot of electricity physics at school in Greece and I was an ace student so my brain would not give up on this. Many a sleepless nights were wasted trying to understand what I...

Thank you for the numbers. My panels do not droop, if anything they are convexing as the bimini is super tight. I also thought about that by reading about it online. i have never seen decent output so as to believe that the panels where ok but somehow the performance dropped.

That is what i plan to do next time im on the boat, i simply did not have the luxury off taking them offline and check them. My alt is 40 Amps and the batteries can keep up. My shore charger is 30 Amps. I was just trying to find out what others are getting from their panels and was wondering why...

If you see the pics I posted, I start off at 12.10-12.20 in the morning. With such a tiny solar output, it is impossible that the batteries will be near fully charged by mid day when full power is available from solar panels. But if we suppose you are right, that would mean that the batteries...

2x140 Ah Bosch Deep Cycle, 3 years old, when not in use they get to absorption and float within a single day according to the Victron. They are not new but I would say they are about 85-90% of their original capacity at least. Never had them below 12v and where usually charged by 2 oclock before...

When the battery starts off at 12.20 in the morning, the charger will give it about 12.8. As the battery slowly charges, the charger gives it more juice, all the way up to 13.8 at mid day. The charger is set up for Victron AGM which is the closest to my Bosch Deep Cycle of all the Victron...

A typical day

Max voltage averages between hi 17 and low 18 volts, but usually its around 14-15 volts 4-5 Amps. At the same time I get around 13 volts 5-7 Amps on the battery side output of the MPPT. But I guess that is normal voltage, right?

So I bought 4 100 watt flexible solar panels of banggood Elfeland sp-37 (here is the link, dont know if it will work for you) https://www.banggood.com/Elfeland-SP-37-18V-100W-1050540mm-Semi-Flexible-Monocrystalline-Solar-Panel-p-1143245.html?rmmds=myorder I installed them and got a victron...

St60, yes please, PM sent

I live in Greece, as soon as they realise that I am a DIY kind of person, they will just shrug their shoulders and say 'the C80 is old, you should upgrade'.
