Please tell me, we have switched from 12volt to 24 volt system. We have 5x200watt 36volt solar panels. 4 deep cell gel batteries 150Amp hour each. MPPT charge controller with built in inverter. On the 12 volt system we got up to 32 Amps and 26volt. Now we only get max 32 volt and 9.9Amp. What could be the problem please?
26V with a 12V system is not possible. Check the settings of your charge controller and adjust it if necessary. How are your panels wired? send me an email for better communication.
@@cleversolarpower Thank you for replying. Much aporeciated. Please give me your email address for possible future queries if you don't mind. We have not used the same charge controller. We actually bought a new 24 volt mppt charge controller. We have found the problem. Have replaced the diodes on panels. Running like a dream now with only 4 panels. Going to use 12volt controller to start a second separate solar system. Once again, appreciate your response.
Vdrop = 2·I·R·L -> 2*5A*0.0009899ohm*50ft= 0,49495V where: 2= wire in two directions I=current through the wire R= resistance per feet of copper wire L= length of wire in a single run in ft
@@cleversolarpower A useful fact about that. The number of litres you quoted is for what's better referred to as a "US gallon". In the UK (And a lot of the old Commonwealth countries), "a gallon" is 4.55 litres. It can cause confusion when something online just specifies "Add a gallon of [XYZ]" without saying whether they mean a US or imperial gallon. It can also really skew things like fuel economy figures when checking car specs on different websites. For example, my car will do 50mpg when quoted on a UK website, but only 42mpg when it's measured in US Gallons on an American site, so knowing which version of "Gallon" is being used can make quite a significant difference. To confuse matters even further, there's also the less common "US dry gallon", which is about 4.404 litres. :)

.05 ohm X5 amp only = .25 v
What am I missing or why does video calculator show .5 volt drop?
Vdrop = 2·I·R·L -> 2*5A*0.0009899ohm*50ft= 0,49495V
where:
2= wire in two directions
I=current through the wire
R= resistance per feet of copper wire
L= length of wire in a single run in ft
@@cleversolarpower thanks so much. I found vd=KIL/ cm works well and taught me I have to account for round trip of wire. Thank you for your help!
what is gallon?
3.78 liters
