A âGroup Assetâ in SAP is almost like a normal asset except that it can have (any number of) sub-assets denoted by Asset Sub numbers. The concept of group asset becomes necessary when you need to carry out depreciation at a group level, for some special purposes such as tax reporting.
With a regular charge controller, if your batteries are low at say 12.4 volts, then your 100 watt solar panel rated at 6 amps at 16.5 volts (6 amps times 16.5 volts = 100 watts) will only charge at 6 amps times 12.4 volts or just 75 watts. You just lost 25% of your capacity! charge controller is used to maintain the proper charging voltage on the batteries. As the input voltage from the solar array rises, the charge controller regulates the charge to the batteries preventing any over charging.
Your solar charge controller acts as a regulator. Controllers monitor the charging voltage of batteries and cut the battery off to keep it from overcharging. When the battery can take more voltage, the controller passes in just enough to top the battery off, no more or less.he purpose of a solar charge controller does not become clear until you gain an understanding of how they work alongside solar panels to move power through your home. First, understand how solar cells work.
