Solar And Renewable Energy Products #3275597

Based in Delhi, we are the key manufacturers and suppliers of PWM Solar Hybrid System. PWM Solar Hybrid System is suitable for handling higher loads. They have a bank of solar photo voltaic modules that are tied to a bank of batteries. This aids in controlling the interface which is a critical component here. It is equipped with a number of features. It aids in keeping a check on the battery voltage and facilitates optimum charging of battery. It has a quick charging mode and a switch over mode. The switch over mode is capable of monitoring the load by switching it over to the unit senses, in case it is unable to bear the load.

Features :

• Monitoring of battery voltage, optimum charging of battery, state of battery charge monitor, low voltage and overload cut out.

• Quick battery charging mode using solar power or mains power or both with the controller sensing SPV module power and switching to mains if voltage is low, as happens in case of rainy conditions

• Switchover of load to solar when monitoring unit senses it can bear the load. Lento controller monitors and seamlessly switches power in milliseconds, making it ideal even for sensitive electronic devices like computers.

• DSP based sine wave output with fixed 50 Hz 230 V sine wave output. This enhances reliability and durability of equipments that are designed to work on sine waves such as air conditioners, refrigerators, tube lights and fans.

• Energy conservation is highest while battery backup is longest in our DSP based solar hybrid systems.

Convenience

• Solar Hybrid DSP uses both Solar Power as well as Mains for charging the battery bank according to parameter priority set, providing the users availability of uninterrupted power supply.

Lentos advanced line of affordable solar chargers are compact, ruggedized for operation in extreme weather conditions and are designed for durability. This line of solar chargers are designed to work in standalone solar power systems where they form an essential link between the SPV modules and the battery. Our solar chargers play a crucial role in maintaining battery health, better efficiency and improved performance.

MOSFET based solar charger incorporates circuitry that senses battery voltage. If voltage falls below a certain value the MOSFET switches on through the PWM controller that delivers pulsed power. As battery begins to charge up the power to it progressively reduces and when the battery is fully charged the circuit switches off delivery of power to the battery keeping it in full stand by condition. This circuitry also prevents over charge of battery that can lead to loss of electrolyte. It works unattended and is simply to operate as well as maintain, with the least part count.

Additional circuitry can be incorporated for automatic switch on of power to lights, such as in streetlights. Circuitry is also incorporated to detect battery temperature and to provide deep discharge as well as overload and reverse polarity protection both at input and output of the charger.
