A "constant voltage" source. Solar panels, for the most part, are "constant current sources". If you have an Imp = 10 amps solar panel (current maximum power)... Under full sun the panel will (for a first approximation) output 10 amps from zero volts to Vmp (voltage maximum power).
During bulk charging for solar, the battery’s voltage increases to about 14.5 volts for a nominal 12-volt battery. When Bulk Charging is complete and the battery is about 80% to 90% charged, absorption charging is applied.
When Bulk Charging is complete and the battery is about 80% to 90% charged, absorption charging is applied. During Absorption Charging, constant-voltage regulation is applied but the current is reduced as the solar batteries approach a full state of charge. This prevents heating and excessive battery gassing.
As the State of Charge (SOC) increases, the battery charging current limit decreases in steps. Additionally, we observe that the battery voltage increases linearly with SOC. Here, Open Circuit Voltage (OCV) = V Terminal when no load is connected to the battery. Battery Maximum Voltage Limit = OCV at the 100% SOC (full charge) = 400 V.
Constant voltage (CV) allows the full current of the charger to flow into the battery until it reaches its pre-set voltage CV is the preferred way of charging a battery in laboratories.
Solar charge controllers put batteries through 4 charging stages: What are the 4 Solar Battery Charging Stages? For lead-acid batteries, the initial bulk charging stage delivers the maximum allowable current into the solar battery to bring it up to a state of charge of approximately 80 to 90%.
