Sorry, that one amp thing was bugging me... basically a 12v system is around 8amps per 100 watts drawn (so something drawing 100 watts an hour, should drawn around 8 amps an hour [8.33 is more precise] at 12v... given the fully charged state is around 13.8volts, and when solar fully running...

Sorry, rather than using bald statement like multiply setup by four: What is the standard voltage you are using? 120v, 240v? Anyway, staying with the 12v scenario. 2.24Kw/d, assuming good power for 8 hours, (24-8= 16hrs); 2/3 of day using batteries. 2/3 of 2.24Kw/24hrs is about 1.45kw/16hrs...

Basically double the number of panels, double the number of batteries, would be the minimum, if this the ONLY thing you are powering. That leaves no fudge for dull, overcast, rainy, days. The consumption of the freezer goes up when you put warm stuff in to freeze (so do that first thing in the...

Use all the available batteries, if they are ok, as parallel, battery banks, if you must continue the 12v system. Ensure that every two parallel battery banks have their own wire back up to the input (preferably at a fuse), all these wires should be equal length, equal gauge), so you are putting...

As an estimate, 10 x 325W panels could be put in two parallel strings (series) of 5 panels - this reduces the volts, doubles the amps available in the DC setup, bought down through a fuse block (15amp DC), combined, and fed into a Victron 250/85 controller (you are below combined Voc). The...

Nope, no arc. After I had everything unhooked, tested, and hooked up again, I connected the Victron controller, but could not get output. I was fortunate that the newest Victron controller was purchased with the push in display (extra cost). After I ran around in circles, I looked up how to...

And I suspect I have the answer>> operator error. As I am using a new meter (my helpful adult children having 'somehow' stuffed the old one) I did not change the plug to the amps circuit input, as required on this meter, which gave me an error in the reading. I am actually surprised it gave me...

No, there is no arc visible. I am measuring using a voltmeter, set to DC amps. The amps are well below meter limit. I am measuring across the end of the wires, before they are connected into the circuit breaker. Volts around 155DC. I had already noted that the amp reading was not what I expected...

I did think about the other way, paralleling the panels, but getting wire to carry that amperage? I think the limit on standard solar wiring is about 20amp over 30 metres, or similar? Most people string their panels in series to obtain higher voltage, and lower amperage, because high voltage/low...

Just looking quickly, I would suspect your maximum voltage, in a string of 10 445W panels in series, will probably far exceed the input capacity of 150v for the controller! You will see two blinking lights, telling you that you have exceeded the maximum rating, and are doing damage. The Victron...

Did you ever get an answer. I have just noted the same thing. I have two lines of series wired panels; when it test across the wires on each series (each is a string of 4 Canadian Solar 325W panels). I get approximately 155V, 5.5 amps; when I combine the two I still read 155v, but only a bit...
