Need Help. New but humble enough to take your advice. I only know so much but I am really stuck. Need solid advice.

Ya controller will only max out at 122voc and 11amp round up. So it would be well within its limit. I may be able to add a few more pannels and keep the voltage the same and ad a string or 2 but like mentioned I would be over the 15 amp fure rating and will need inline fuses or a pannel. I am more interested in were the fuses go for the battery bank and how to fail safe the system incase of a current run away. I have heard it happens so fast the fuse cant blow in time and it hits your battries at full voltage. I know Victron is good but there should always be contingencies.

You can look up expectations for Solar Harvest @ Edmonton to get you an idea;

PVWatts

Estimates the energy production and cost of energy of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, small building owners, installers and manufacturers to easily develop estimates of the performance of potential PV installations

I like to use Blue Sea battery terminal fuses, but if you go big enough on your battery bank “Class T” Fusee should be used close to the battery terminal ( positive ) in an appropriate holder.










I like what @Hedges posted here regarding battery “AIC”;

There has been a sobering thread that has caused many of us to pause & evaluate the massive amount of energy stored in these seemingly bigger & bigger battery banks & to protect with fuses that can “open up” & interrupt the current;

A very basic sketch of what you want to build can be very helpful on the forum to flesh out your design.

Very good information and thank you for sharing. I will get everything mapped out on my roof tonight and have a drawing made up for everyone to critique. Been a bit difficult since everyday is like 32-34c. I hate the heat. Even in the house its like 32-33c. Been rough the past week. But ill get a diagram tonight and we can all go from there. I will also gonthrough all of your data and see what I will need.
