The proposed 48V solar battery charger circuit with high/low cut offfeature can be witnessed in the following diagram. The functioning of the circuit may be understood with the following points: The IC 741 is configured as a comparator and is appropriately stabilized from the high 48V input using zener diodes. . The above 48V solar battery charger circuit with high, low cut-off may be modified with these specifications by introducing a window. . Another version of a 48V automatic battery charger cricuit using a buzzer indicator can be studied below: The idea was requested by Nadia, please refer to the discussion between Nadia. . The operations involved with the first diagram above gets much simplified if a relay stage used instead of BJTs, and mosfets. As can be seen in the above updated diagram, the relay stage is in the form of two 24V relays in. . Do not connect the charging voltage from the right side. Keep the 10k preset slider arm towards ground initially. Connect a DC input using a DC variable power supply from the Battery side on the LEFT of the circuit. Adjust this. [pdf]
Due to low current, battery needs 18 hours to fully charge the battery but sunlight is only available for 12 house max. in conclusion at the night time the switching circuit and LED light consume 10 to 12w of power from battery and at day time the solar panels refill the battery. Little bit tricky but its work!
1. Solar panel should continue charging battery not beyond 56 V. 2. In the event of battery discharge, the charging process should resume again only when it reaches 48V. In other words hysteresis should be maintained. 3. Battery should continue supplying power to load when battery voltage remains in between 42 - 56V.
The solar panel supplies the peak voltage of 6 V, at 500 ma during daytime, which charges the battery as long as this voltage is available from the solar panel. The resistor Rx keeps the charging current to a safe lower level so that even after the battery is fully charged, the minimal current does not harm the battery.
The circuit normally charges the connected battery at constant current through the power received from the solar panel, and reverts to DC power from an AC/DC adapter in the absence of solar energy (during night time). Let's the read the request in more details: 4.2.1 The following circuit goes in response to the added comment by Juan.
The following diagram shows an extremely simple 48 V solar charger system which allows the load to access the solar panel power during day time when there's optimal sunshine, and features an automatic switch over to battery mode during night when the solar voltage is unavailable:
The controller circuit is expected to perform as follows. 1. Cut off solar supply to battery when its voltage reaches approx 56V and maintain appropriate hysteresis to avoid frequent switching of power MOSFET. So the solar supply to battery would resume again only when the battery voltage reaches approx 48 V. 2.

is a three-stage charging procedure for lead–acid batteries. A lead–acid battery's nominal voltage is 2.2 V for each cell. For a single cell, the voltage can range from 1.8 V loaded at full discharge, to 2.10 V in an open circuit at full charge. varies depending on battery type (flooded cells, gelled electrolyte, ), and ranges from 1.8 V to 2.27 V. Equalization voltage, and charging voltage for sulfated c. [pdf]
It takes 8 to 16 hours to fully charge a lead acid battery, depending on the size of the battery and the charging current. This applies to both AGM and lead acid batteries for cars.
A lead acid battery charger is a device used to charge lead acid batteries. Lead acid batteries are common in many applications, such as automotive and marine applications. There are many different types of lead acid battery chargers on the market, each with its own advantages and disadvantages.
Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating.
Lead acid batteries are strings of 2 volt cells connected in series, commonly 2, 3, 4 or 6 cells per battery. Strings of lead acid batteries, up to 48 volts and higher, may be charged in series safely and efficiently.
The maximum charge rate for most lead acid batteries is about 10 amps per hour.
To charge a 12V flooded lead acid battery, you should use 2.40-2.45 volts per cell as the charging voltage. This will ensure the fastest charge without damaging the battery.
