Cerbo GX with two battery banks of different voltages
I was wondering if the latest Cerbo build copes better with multiple battery banks that operate on different voltages. In the past it was possible to have two banks of different voltages, but to get to some of the metrics for the "secondary"
Pros and cons of 1 big battery vs several small ones?
For off grid / solar power systems, it is usually much better to charge the batteries are around a 10% to 13% or so rate of charge--Simply, because the sun is not up in the sky long enough to fully recharge a well discharge battery bank at 5% rate of charge....

I want to charge 3 separate battery banks from one solar array
Why can you not connect all three inverters to one large battery bank+solar array(s)+solar charge controller(s). If staying with three separate banks, having the array split with a controller and array for each bank seems best IMHO. Having multiple MPPT controllers on a single array is problematic. I think you''d need to find a big enough
How To Set Up Battery Bank For Solar: Essential Steps For
A solar battery bank consists of multiple batteries connected to store electricity produced by solar panels. Batteries can be lead-acid, lithium-ion, or other types, with varying capacities and lifespans. For example, a typical lithium-ion battery may last 10-15 years, while lead-acid batteries may need replacement every 3-5 years.
Multiple Battery Banks
I need to work out a way to efficiently charge one independent battery bank from another of the same voltage. I have two 12v independent battery banks that are entirely off-grid. Both banks are lithium iron phosphate. One is fixed and immobile-- it consists of 4xLishen 280 ah, with 100 amp BMS''s.
Connecting Multiple Charge Controllers one Battery Bank
Would it be possible for me to install an external solar charger parallel to the solar inverter to the same battery bank? If yes, I have my solar inverter settings as follows:-Bulk Charge 29.2V-Float Charge 28.2V-Cut-Off voltage 21.5V-Maximum Charge Current 40A
Parallel Battery String Topologies, solution
Hi all. I am designing a multi-house solar PV system, where multiple (2 to 8) DIY LFP 48V battery banks working in parallel. This multi-string battery will have capacity in the 25-100 kWh and feed multiple 48VDC
Multiple Battery Banks
If I top charge/balance Battery Bank #1 (the 24v in 4s4p). Then I do the same with Battery Bank #2. Then I connect both battery banks to the same bus bar. Then make the connection to the shunt/fuse. This would be essentially combining both battery banks into 1 (at 580ah), running at 48v.

Multiple MPPT''s and Connection to Battery Bank
I am in the process of doubling the wattage and battery capacity of my solar charging setup of my overland truck. To that end I am adding a second 100/50 victron smart solar unit to handle the additional four 200w panels (wired per Will in 2x2 series and parallel for 24v). This will work to charge a four battle born 100ah 24v battery bank.

Multiple Battery Banks
I use a bus bar for the battery banks, each bank has a fuse & switch. Then from the battery bank bus bar to a fuse & switch to the main bus bar with the charge controllers & inverters. Works great with 2 battery banks, plan is to add a new battery bank every 3 or 4 months, as funds permit.
How can I connect solar banks in series ? in order to have out
You cannot connect multiple generators, be they gas generators or solar genertators, into the same power network. Think of it for a second. You can connect a solar bank to a battery bank, and then from battery bank you power everything. During the day, power goes from solar bank, when it''s night battery bank takes over and when the next
Parallel Battery Bank: Direct Connector or Bus Bar? : r/SolarDIY
Batteries in direct parallel connection: second battery connects to first batter, first battery goes to bus bar (which also has the charge controller and inverter) Uh oh! Sounds like you''ll end up with one battery having both connection leads going to the rest of the system on it. Uneven resistance. Bad for battery health of the bank as a whole.
"Break free of 4S4P" w/ Multiple Battery Banks?
So, my original question about being using multiple battery banks with some kind of automatic battery bank selector/switcher which switches automatically to another bank as the current bank gets discharged to a certain level went unaddressed for two reasons maybe. 1.

Victron battery Isolator for charging 2 different battery banks?
From what Ive learned about them, one would connect both battery banks to a common ground, a charging source is connected to the input, one battery bank to output #1 and one battery bank to output #2. The isolator keeps both battery banks completely separate from each other yet allows both to be charged by the same charging source.

Connecting more than one charge controller to the same battery bank
However multiple other people say no problem, as long as both charge controllers are set up the same. One did say : - There might be a problem with flooded lead-acid batteries where they equalize every month. If you have multiple charge controllers attached to the battery bank they equalize more frequently, Which is not good for the battery.

Different sized battery banks on a single inverter
Two or more batteries working together is a Battery Bank. Each Battery Pack must be independently fused. Multiple Battery Packs can make up a Bank but there are practicalities that come into play as a bank gets larger. LFP banks can be added to over time, unlike Lead Acid which starts its age cycle right away.
Charging from multiple sources | DIY Solar Power Forum
Also very important that the sum of all charge currents do not exceed the recommended max charge current of the battery bank. Note: Multiple chargers only offer benefit when the battery is below the absorption voltage. Once the absorption voltage is hit, it is now a voltage limited charge and thus current will be lower than the sum of all
Multiple Battery Banks across Several Paralleled Inverters???
I posted this in the other thread about parallel inverters with separate battery banks, I don''t know if it''s specific to victron or not: "Every DC connection (on every Multi/Quattro and on every battery) has to be connected together to a single DC bus.Do not build systems with separated batteries on multiple (separated) DC bus structures connected to subsets of the
