PV Charge Controller
PVC - 7830 / 7840
User's Manual
LCD Display (Monitoring Screen with back light)
Precautions:
1. Before using the PVC PV Charge Controller, read all instructions and cautionary markings on the
controller, solar panels and batteries.
2. This PV Charge Con trol ler is design ed for ind oor us e for 12V or 24V sol ar s ystem, do n ot ex ceed the g iven
power rating of charge and load given in the specifications.
3. Do not attempt to repair the controller. Incorrect re-assembly may result in a risk of electric shock or fire.
4. PV panels produce power when ex pos ed to light after disconnec tion k eep the terminals well iso lated. C over
them with opaque material such as clothe before installation.
5. To reduce risk of electr ic shoc k, disc onnect all wiring before at tempting any maintenanc e or cle aning of the
PV system.
6. Working in the vicinity of lead acid b atteries is dangerous as the y produc e explosive gases so mak e s ure no
naked fire or spark is present when working near batteries. Sufficient venti lation must be provided to the
battery compartment. Eye protection should be used.
7. Be extra cautious to reduce the possibility of dropping a metal tool onto batteries. It may spark or short-circuit
batteries or other electrical parts that may cause explosion.

Introduction
The PVC is designed for use with all types of solar panels, lead acid batteries and LiFePo4 batteries for 12 and 24
V solar system.
1. The LCD with control back light displays critical live information of PV charging voltage, current and battery
voltage, charge status and load condition in one screen.
2. There are 15 parameters that can be viewed, set or adjusted using the 4 buttons.
3. Three Stage charging plus Equalization Charge for Wet battery .PWM charging for Absorption and Float
stages.
4. Selection for no float charge is available.
5. Adjustable voltage and delay time for Bulk, Float, LVD and LVR.
6. The Remote Control for trigger or on-off control of external devices, (e.g. Alarm, relay, on/off of charger or
inverter etc.) to operate in the same time as the load control programs and LVD / LVR.
7. Two Night Light Load and Two Day Light Load Programs.
8. One adjustable PV voltage for Sun Rise and one for Sun Set reference time line.
9. One USB charging port for Apple or Android device
10. Remote battery voltage sensing and optional remote temperature sensor.
