Returning the last 20 to 25% of the charge to the battery is also a complex and time consuming process. It may very well take as long to return the last 20% of the battery charge as it took to return the first 80%. Second, and just as important, is the way that battery charger manufacturers rate the output current of their charger products.

Due to this, a Power Conversion System (PCS) or Hybrid Inverter is needed. These devices are much more dynamic than standard inverters as they can convert power bi-directionally. This means DC power from the battery can be converted to AC power for use with grid or electrical loads, and AC power can be converted to DC power to charge the battery.
Battery Cell Balancing: What to Balance and How
A. State of Charge (SOC) Unbalance State of charge unbalance is caused by cells being charged to different state of charge (SOC) levels.

In other words, if the state-of-charge of a fully charged storage battery is 100% (SOC = 100%) and is 0% when fully discharged, (SOC = 0%), respectively. So for instance, a 300 amp-hour battery at a 70% state of charge will contain 210 amp-hours of stored energy, and at a 50% state of charge the same battery will contain 150 amp-hours, and so on.
