GSM and SNMP Add On Solutions

GSM and SNMP Add On Solutions

In organizations where USP units are deployed on a large scale it becomes necessary to monitor and evaluate their performance. This is not practical if done manually. Lento’s innovative GSM and SNMP add on solutions take care of this issue. The system allows remote monitoring of USP through LAN and Internet. Centralized remote monitoring can track performance of each unit, maintain logs as well as detect fault. In addition to reducing dependence on human resources this solution also allows administrators to allow computers to hibernate before a UPS is shut down for maintenance and thus preserve valuable data.

Features:

Lento SNMP and GSM solution has advanced state of art features such as:

Remote monitoring through LAN or WAN networks, Facility to use multiple screens to evaluate a number of USP or a number of factors, POP up messages with alarm, Hibernate facility to save power on all clients connected to LAN, Self diagnostics and detect problems as well as ability to send notifications through mail, Password protection, Easy to use graphical user interface.

Key features of Lento SNMP Manager

Lento SNMP software is designed to monitor multiple USP units simultaneously and display warning messages in case of any malfunction in any of the units, It has inbuilt facility for Pop-up messages and warnings for low battery, mains MCB trip, overload and over-temperature, Monitors all parameters such as UPS ID & IP address, each unit’s input and output voltage and frequency, battery voltage & status, load, output status on battery/mains and communication status, Data logging for each UPS with time and date for historial analysis purpose, Protection logging with IP address, date and time, Options of digital, graph and analog views, Smart trap finds faults related to variations in output voltage and frequency, temperature, overload and battery status, SNMP client easily installs on client computers in LAN in addition to main server where the Manager is installed, Web management tools included  to allow remote monitoring of status of each UPS from any location at any time as well as monitor the UPS through WAN static IP address.

Lento SNMP solution is developed keeping in mind usage patterns of telecom industry and banks as well as organizations that make use of a large number of

LENTO Smart MPPT Solar Chargers

Lento offers next generation smart MPPT based solar chargers for maximum efficiency and highest performance required in demanding situation. MPPT stands for maximum power point tracking and Lento’s smart MPPT solar chargers play a crucial, central role in stand alone and hybrid solar power installation. MPPT increases energy transfer efficiency by as much as 30% by calculating maximum voltage available from the SPV modules at which maximum power is available for charging and sets the charging current accordingly. Output from SPV modules can vary considerably according to changing weather conditions and incorporation of MPPT means the charging conditions are always optimized by covering extra voltage to amperes and thus speeding up the charging process. Lento uses high grade components to assure best performance and extended life of the unit.

Lento’s smart MPPT Solar chargers also play a dual role. The MPPT microprocessor and DSP based module constantly measures the load current on the battery and prevents deep discharge thereby extending battery life.

Features:

Microprocessor controls all parameters,Constant tracking of voltage from SPV modules and automatic optimization to amperes,Automatically detects type of battery connected and its Ah capacity to optimize charging current,Regulation of current drawn by load connected to the batteries,Prevention of overcharging,Over temperature, transient over voltage and reverse current flow protection,Prevents deep discharging of battery,Reverse terminal protection for SPV terminals and battery terminals,Short circuit prevention,PWM charging, automatically selects 12, 24 or 48VDCbased on SPV input voltage and battery connected to the unit,Charging current and voltage can be adjusted automatically or manually for Gel, tubular or flooded lead acid batteries,Constant monitoring of input and output currents and voltages with automatic adjustments

Lento MPPT intelligent solar chargers are the next generation solutions for optimized performance, whether it is in compact portable units, solar home power installations or larger independent stand alone SPV power generation systems.
