You can Parallel AIO's to incxrease their output but also their generation capacity as well. Most brands like MPP/Growat/EG4 can also be networked so they work together.
Batteries can also be put in parallel and they will divide both load & charge between them proportionately to their capacities.
When paralleling battery packs, it is essential to use identical cabling (AWG) and identical lengths between them all.... Otherwise charge/discharge imbalances
will occur. Most notably when charging, you will see different packs taking different voltages, the difference is an indicator.
Every Battery Pack should be Fused or be Breakered.
Below is a one of my generic diagrams showing how a paralleled AIO system is setup.
- You can have as many batteries as you want in a Battery Bank.
- They can also be added over time as there is no issues with doing so using LFP.
- The only constraint is the capacity to charge the Bank (remember the batteries divide load/charge between them)
- For ESS (Energy Storage Systems) most folks will charge their banks around 0.2 - 0.3 C Rate on average.
48V100AH Battery can take 0.5C / 50A Charge. 0.2C = 20A & 0.3C = 30A
! We have several members running 4-6 EG4 Batteries in a Rack as 1 bank to a single EG4 AIO, when using the same "Product Family" it is best of course to use the Battery to AIO Communications for a Closed Loop smart system.
For Clarity:
A Battery = a Set of Cells + a BMS built into an independent "Battery Pack".
A Bank = a Set of Complete Batteries assembled together to deliver more storage capacity (AH). This can be either/or series/parallel batteries.
Hope it Helps, Good Luck
