It is recommended to remove the protective film cover from the LCD screen before operation. 5.1 Installation Notes This charge controller must only be used in PV systems in accordance with requirements given in this user manual and the specifications of other system components provided by their manufacturers. No energy source other than a PV generator may be connected to the PV charge controller referred herein. PV-modules must always be disconnected prior to the installation and adjustments of the charge controller; Make sure the circuit breaker, fuse or disconnects of battery terminal are turned off. Double check whether battery voltage meets the voltage range of Charge Controller. Batteries store a large amount of energy, never short circuit a battery under any circumstances. We strongly recommend connecting a protection fuse directly to the battery terminal for protection in case of short circuiting the battery. Batteries can produce flammable gases. Avoid provoking any sparks, using fire or any exposed flame close to any batteries, ever. Make sure that the battery room is well ventilated to disperse any gases. Only use insulated tools and avoid placing (any) metal objects near/close to batteries. Be extremely cautious when working with batteries. Wear eye protection by all means. Have fresh water available to immediately wash and clean any contact with battery acid. Get immediately medical aid in case of any hazard that may occur. Never install/handle with batteries alone. Avoid touching or short-circuiting wires or terminals. Be aware that voltages on given system components, terminals or wires can be a multiple of battery voltage. Only use insulated tools, stand on dry ground, and keep your hands always dry and protected by proper (approved) electrician gloves when working on PV-Systems. Prevent any water, ever, from penetrating the controller, outdoor installation must avoid any direct sunlight and penetration of any water (e.g. rain) and humidity. After installation make sure that all connections are properly tighten, eliminate any electrical loose connections to eliminate by all means any hot electrical connection spots. 5.2 Mounting Location Requirements Do not subject the PV charge controller to direct sunlight or any other heat sources. Protect the PV charge controller from any dust, dirt and moisture. Mount it flat to a vertical wall. Must be a non-flammable material. Maintain a minimum clearance of 15 cm below and around the controller to ensure unhindered air circulation. Mount the PV charge controller not too far from the batteries (for accurate voltage sensing least lessening). Mark the position of the PV charge controller fastening holes on the wall, drill 4 holes and insert dowels, fasten the PV charge controller to the wall with the cable openings facing downwards. WARM AIR >15CM COOL AIR >15CM 7 5.3 Wiring Specifications Wiring and installation methods must comply with national and local electrical code/specifications. The wiring specifications of the PV-system battery must be selected according to rated currents. Please check following table for wiring specifications: Model Rated charging Rated current discharging current Solar wire diameter (mm²/AWG) Battery wire diameter (mm²/AWG) Load wire diameter (mm²/AWG) Max20-EU 20A 20A 5/10 5/10 5/10 Max30-EU 30A 30A 6/9 6/9 6/9 Max40-EU 40A 40A 10/8 10/8 10/8 Max60/6048-E 60A 30A 16/5 16/5 6/9 ! The indicated cable/wire sizes are for reference only. If longer runs between the PV array and the controller or between the controller and the battery are required, than larger capacity cables must be used to reduce voltage drop and improve system performance. 5.4 Connection We strongly recommend connecting a fuse directly to the battery terminal to protect from any short circuit in the battery circuit. PV-modules generate current whenever light shines on them. The generated current is directly proportional to the light intensity. Even low levels of light, will deliver the PV-Modules no load, full voltage. It is thus utterly advisable to protect PV-modules from any incident light during installation; Never touch uninsulated cables (ends), only use electric insulated tools, and make sure that the wire cross section is adequate for the PV module operating currents. Connections must always be conducted in the sequence as described below Relay Inverter WARNING: The PV-module/array can produce open-circuit voltages in excess of 100 Vdc when exposed to sunlight. Pay highest attention to this fact. WARNING: Risk of explosion! In case the battery's positive and negative terminals or leads get ever in touch, i.e. short-circuited, a fire or explosion hazard might get triggered. Always pay maximum when handling batteries and related circuits. 8 CAUTION: 1. Should the temperature sensor be short-circuited or damaged, the controller can charge or discharge the battery at the default 25 ºC. 2.If a power inverter is used the system, it should be connected to the battery via a DC relay. Do not connect it to the controller's load terminals. 1st step: Connect loads Connect the load cable with the correct polarity of the right-hand side pair of terminals on the solar charge controller (with the lamp symbol). To avoid the presence of any tension on the cable/wires, please connect these first to the load before connecting them to the charge controller. 2nd step: Connect the battery Connect the battery cables observing the correct polarity to the center pair of terminals (make sure you identify the battery marking/symbol on the controller casing!) of the PV charge controller. Pay greatest attention to polarity. Never, ever invert the plus+ and minus- poles). 1)Should your system be nominal 12 Vdc, make sure the battery voltage is between the 5.0and 15.0 Vdc voltage range; 2)for 24 Vdc nominal voltage, the battery voltage should be within the 20.0 to 30.0 Vdc range; 3)for 36 Vdc nominal voltage, the battery voltage should be within the 31.0 to 42.0Vdc; 4)for 48 Vdc nominal voltage, the battery voltage should be within the 42.0 to 62.0Vdc. If the polarity is correct, the LCD on the controller will begin to display those. 3rd step: Connect the solar module When connecting the PV-Module make sure to cover it from incident sun light. Double check the PVModule will not exceed the maximum permissible input current of the Charge Controller (please refer to the section Technical Data). Connect the solar module connection cable to the correct polarity of the left pair of terminals on the solar charge controller (with the solar module symbol). 4th step: Final work Tighten all cables connected to the controller and remove all the remains around the controller (leaving a void of minimum 15 cm). 5.5 Grounding Be aware that the positive terminals of controller are interconnected and therefore bear the same electrical potential. If any grounding is required, always do this on the positive wires/terminals. 9 6, Operation 6.1 LCD Display 6.1.1 Status Description Item Icon Status Daytime, not charging PV array Daytime, charging Night PV voltage current and ampere hours The total charge ampere hours of the solar panel Battery Load Battery capacity Battery voltage(Set Charging target voltage for lithium battery) Battery current Battery state of charge(in %) Temperature(Clear external Bluetooth Device Password) Battery type(Programmable) Load voltage(Set Low voltage protection voltage) Load current and ampere hours The total discharge ampere hours of the load Load mode(Programmable) The load is on The load is off Fault Fault indication, see 6.1.4 !
