How many amperes of battery are required for a 24v300w photovoltaic panel

Solar Panel Wiring Guide

To charge a 12V battery bank, dependent on the charge controller, approximately 7V is required between the absorption voltage requirement of the battery and the solar panel Voc. I.e. a calcium 12V battery that requires 14.8V absorption voltage, will need a panel with at least 21.8Voc. Most solar panels are approx. 23Voc.

What size charge controller for a 300w solar panel?

If you are charging one battery with your solar panel, add 10% to 25A which gives us 27.5A. If you are charging two batteries with your solar panel then add 20% to 25A which gives us 30A. Therefore, for a single battery system, you would need at least an 27.5 Amp Charge Controller; for two batteries it''s 30 Amps or higher.
