Lento Industries Private Limited

Dilshad Garden, Delhi

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.

Salient Features

• Power Saving through No Load Shutdown Feature.

• Monitoring/Data logging feature for better system information at user end (optional).

• DSP based design with absolute and stable sine wave output voltage & frequency.

• State of art MOSFET based PWM technology with greater efficiency at lower cost with dynamic stability.

• Three Stage solar charging (TSSC) suitable for all types of battery charging.

• Combined mains and solar intelligent constant current charging with solar power priority.

• Maximum Solar Power Utilization during charging and backup mode.

• PV availability, battery charging from solar power indication with display on LCD and LED.

• User friendly, feather touch control and selection switches with LED indication on front panel.

• PV pole reversal protection indication on LCD

• Deep discharge battery charging from mains as well as solar.

• More back-up being a sine wave UPS (ASIC Control).

• No humming Noise (Silent UPS)

• Protections such as Mains Fuse Trip, Overload, Short circuit, Battery low, over temperature indication with buzzer as well as display on LCD available.

• Mains available, battery charging/Charged and its voltage indication provided on LCD display as well as LED.

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.

MPPT Solar Hybrid System is a next generation smart solar charger that ensures high performance and maximum efficiency. It plays a major role in hybrid as well as the standalone solar power installation. It accentuates the energy efficiency by 30%. The outputs in the SPV modules can differ with changes in weather conditions. Our products have a better durability and longer life. Based in Delhi, we are the leading supplier and manufacturer of MPPT Solar Hybrid System and our system is aimed at achieving high performance and better efficiency.
