A flow battery is a rechargeable in which an containing one or more dissolved electroactive elements flows through an that reversibly converts to . Electroactive elements are "elements in solution that can take part in an electrode reaction or that can be on the electrode." Electrolyte is stored externally, generally in tanks, and is typically pumped through the cell (or c. [pdf]

Turns out you need about 140 watt solar panel to fully charge a 12v 120ah lead acid battery from 50% depth of discharge in 7 peak sun hours using an MPPT charge controller. .
Note: Not sure what peak sun hours are and how to calculate them? Follow our guide about peak sun hours. .
Use our above solar panel size calculator and follow these steps: 1. Enter battery capacity in amp-hours (Ah):I have already put 120ah for you. 2. Enter battery. To effectively charge a 120Ah battery, you typically need around 300W of solar panels. Use one 300W panel, two 150W panels, or three 100W panels. Ensure your configuration fits your RV space. Also, consider charging times and usage scenarios to optimize efficiency and performance. [pdf]
