batteries
You probably don''t need another controller. If you connect your panels in series - i.e. one string - you won''t exceed 15A. You could connect them as 2 strings of 2 and that would be 30A in total. Only if you connect them all in parallel will you exceed 30A. You should check out the maximum input voltage of your MPPT.
Connecting Two Charge Controllers To One Battery Bank | What …
Additionally, it may be cheaper to buy two 30 amp charge controllers (that give you 200 Volts of solar panels charging your batteries at 60 amps) instead of one 60 amp charge controller.

dual inverter chargers and battery bank | DIY Solar Power Forum
Hi, Suppose I use dual inverter charger-inverters, and I use a roughly 1200AH Lithium battery bank (300AH per 12v battery). Should I make it one battery bank and connects to two inverters or should I make it two separate battery banks (600AH each) and connect them to inverters separately...
How to connect two solar panels to one battery?
You can connect two solar charge controllers to the same battery bank if the total charging current of your solar panels exceeds the capacity of a single controller. Each controller will operate independently, and their outputs will not interfere with each other as long as they are set with identical configurations.
Victron battery Isolator for charging 2 different battery banks?
The isolator completely "isolates" the two battery systems from each other while allowing them to draw current from a single charging source. In other words, current can travel only one way-INTO the batteries from a common charging source. Current cannot travel "backward" from one battery bank to the other.

Powering Off-Grid: Choosing The Right Battery Bank For Solar
Building a battery bank for solar panels involves choosing the right size and type of batteries, as well as properly connecting them to create an efficient and reliable system. Now that you understand the basics of battery banks, let''s dive into the different types of batteries you can use for off-grid systems.
Two Inverters on one Battery Bank ‣ Clever Solar Power
The total power will be: 20A x 12V = 240W. So you can only have a 240W inverter on a 12V, 100Ah lead-acid battery. Now, lithium has a C-rate of 1. Using the same example of a 12V, 100Ah battery: 1 x 100Ah = 100A. 100A x 12V = 1.200W. We can see that we can have a larger inverter if we use lithium.
Can You Connect Charge Controllers in Parallel? (Yes, Here''s …
The answer is yes, you can. In fact it is the most practical solution for off the grid systems with large solar arrays and batteries. Solar charge controllers can be connected in parallel to meet the requirements of high powered solar systems.

Multiple charge controllers vs. one high current unit?
128. May 17, 2020. #3. Larger controllers can often handle higher voltage like 150v. Smaller controllers may be limited to only 100 volts. If you plan to increase the size of your array the additional voltage overhead could be a benefit of a larger controller. That plus two small ones may cost more than one large one.
can you hook two battery banks to one inverter?
Actually if you put a large steering diode on the line from each battery, the batteries would not interact, assuming you still have two charge controllers. You will see a 0.6 volt drop across the diodes. They will not be in parallel this way but both can feed the inverter. This might not be an ideal design but it is not an impossible thing to do.
Can I use 2 Solar controllers in the same system?
Yes you can have 2 (or more) MPPTs on the same battery bank. If it was not possible, you would never be able to have, more panels, than can be handled by 1 MPPT, in 1 system. And we know that is possible. Any MPPT (or PWM) solar charger, has a limit to how much Wp it can handle, eg. the max Wp of a 100/150 or 100/250 SmartSolar is 5 800Wp.
