HLS series PWM solar charge controller is a low cost & reliable product for use as home lighting system or solar street light charge controller. The product is for use with single 12V battery and can give charging current upto 8A. HLS series comes in plastic body and has 4 DC load terminals, so multiple DC lights / fans can be connected simultaneously.

Perfect solution to charge batteries of normal inverters already installed at Petrol Pumps / Institutes / Offices / Schools using solar power. Thousands of units already installed throughout India and helping customers to save on electricity cost.

PPL series PWM solar charge controller is a zero drop microprocessor based device with DC load terminals. It is a low cost solar charge controller for battery charging using solar power and for running DC loads such as DC fans, DC LED light, etc. The DC load can supply 20A of load current at battery voltage. If battery voltage is gets too low, then the DC load is shut down to protect battery from deep discharging. Once battery voltage becomes sufficient to run DC load, the load is switched on automatically. There is also a jumper setting on the product to run DC load only from dusk to dawn. This feature makes PWM-PPL series suitable for use in solar street light applications where high battery charging current is required.

MPPT Charge controller Generation 5 (CC-MPPT-Gen5) is the latest MPPT Charge controller from Systellar Innovations which can charge a battery bank with up to 100A current.  CC-MPPT-Gen5 can be used to charge large battery banks of any chemistry on solar power at isolated sites. It can also be used to charge EV batteries in a truly carbon generation free manner.

Models:

• Gen5 LV for maximum Battery Bank End of Charge voltage up to 60V, Max solar panel V_oc 190V, suitable for nominal battery bank voltage up to 48V
• Gen5 HV for maximum Battery Bank End of Charge voltage up to 250V, Max solar panel V_oc 380V, suitable for nominal battery bank voltage up to 180V

CC-MPPT-Gen5 is field programmable for any of the following battery chemistry:

• Li-ion
• LiFePO4
• Ni-Cd
• SMF Lead-Acid
• Flooded plate Lead-Acid
• Tubular Lead-Acid
• Gel Lead-Acid

Battery bank configuration is flexible. It can consist of a number of batteries each consisting of a specified number of Cells e.g. 48V nominal battery bank consisting of 4 batteries, each battery consisting of six 2-V Lead-Acid cells. Alternatively, it can consist of a number of cells e.g. 41 Ni-Cd cells constituting a battery bank of 49.2V nominal. The default charging thresholds like ‘End of Charge’ voltage; ‘Trickle Charge’ Voltage may be modified by the user either on the Battery Bank level, battery level (in case the unit of battery is defined) or on cell level.

CC-MPPT-Gen5 has a 64×128 dot graphical LCD display for comprehensive display of the charging voltage, current and power levels. There are three LED indicators to indicate PV input, charging state and fault. It has a 5 key keyboard (INCR, DECR, NEXT, SEL and ESC) and a beeper for easy editing of parameters and other functions.

CC-MPPT-Gen5 has an RS485 MODBUS RTU interface which can be used to monitor the charge controller performance using an IoT monitor. It has an external temperature sensor for the battery bank and an internal temperature sensor for the heat sink. A general purpose relay drive output (12V DC) is available which can be used to drive a Power Saver Relay, Load-On relay or a Night Switch. Another relay drive FAULT_NOT is available for activating an external alarm in case of a system fault.
