Page 2: Important Safety Instructions
1. Important Safety Instructions This section contains important safety information. Before installing or using the unit, READ ALL instructions, and the provided cautionary markings. The unit contains no user-serviceable parts. See Warranty section for how to handle product issues. Warning: Fire and/or Chemical Burn Hazard Do not cover or obstruct any air vent openings and/or install in a zero-clearance compartment. - Page 3 Noted: The charge controller always need to connected to a battery to test and function properly. Thank you for purchasing the Nature Power 30A Digital Solar Charge Controller. With our state of the art, easy to use design, this product will offer you a reliable service to convert your solar energy to charge your low voltage battery system in an effective and efficient way.
- Page 4 3. Understanding the unit Caution: This unit is designed for use with V or V nominal Battery Systems only Solar Panel Battery DC Load Chassis Ground Terminals 1 and 2 are the input port for the solar panel connection. Terminals 3 and 4 are used for the battery connection. They act as both an output port, for charging the battery from the solar panel, and an input port for discharging the battery to the DC loads (if any) through the controller (on terminals 5 and 6).
- Page 5 Push Buttons Functions: (‘Menu’, ‘Enter’, Up ‘ ’, and Down ‘ ’). In Normal Operating Mode Press once to enter the Setting Display Mode to read the unit settings without the risk to change them accidentally. Once in the Setting Display mode, press the Up/Down buttons to scroll circularly through the parameters settings (Real Time Clock, Battery Type, Lithium/Program Bulk Voltage, DC-Load Voltage Disconnect and Reconnect on terminals 5-6, and the start and duration of the timers).

4. Three-stage charging algorithm: The unit provides a 3-stage charging algorithm having a Bulk, then Absorption and then Float stage sequence. During the Bulk stage, the battery accepts all the possible current from the solar panel (if available) in an effort to charge the battery and so raising its voltage. Once the battery voltage reaches the maximum one (depending on the setting), the unit passes from Bulk to Absorption stage, keeping that maximum voltage by reducing the charging current if necessary under a PWM... - Page 7 6. Display Functions and Symbols: These Symbols show the charging and discharging status in the Normal Operating Mode only Symbols shown in all the modes and according to the specific conditions at the moment Push buttons with multiple functions, according to the specific operating mode at the moment 7.
- Page 8 The solar panel is detected but does not have enough voltage to charge the battery. The DC-Load is ON and there is no load, or it is very low to be detected. The solar panel is unavailable (e.g. at night or disconnected). The DC-Load port is ON and the load is drawing current from the battery.
- Page 9 8. About the net battery charging and discharging conditions shown on the display: As already mentioned in the previous table, the current in Amps shown on the display is the net one, being the result of the one provided by the solar panel minus the one being drawn by the DC loads connected to the terminals 5-6 of the unit (if any).

Page 15: Operation And Maintenance
10. Operation and Maintenance: The following periodic inspections and maintenance tasks are highly recommended for best performance. Verify the battery state of charge regularly. Check for any rusting or corrosion around the battery terminals. Verify that the connected solar panels and loads do not exceed the unit maximum ratings as per the tables in section #5 and in the specification section. - Page 16 Case1: The three timers are set up to be ON at different times and without overlapping each other. As a result, the DC-Load port turns ON and OFF three times a day. Case 2: One of the Clock timers is overlapping another timer. As a result, the DC-Load port turns ON and OFF two times a day.
- Page 17 12. Checking the controller (fast test) after installed for the first time a. Select a time of the day with a good sunlight condition, enough for getting at least 17-18Voc from the solar panel array when it is in open circuit (disconnected from the controller). b.
