EN 1. PRODUCT INTRODUCTION NL Charge current up to 70 A and PV voltage up to 150 V The BlueSolar 150/70-MPPT charge controller is able to charge a lower nominalvoltage battery from a higher nominal voltage PV array. The controller will automatically adjust to a 12, 24, or 48 V nominal battery voltage. FR Synchronised parallel operation of up to 25 units Interconnect the charge controllers with RJ45 UTP cables and they will automatically synchronise.
2. SAFETY INSTRUCTIONS Danger of explosion from sparking Danger of electric shock ● It is advised to read this manual carefully before the product is installed and put into use. ● This product is designed and tested in accordance with international standards. The equipment should be used for the designated application only. ● Install the product in a heatproof environment. Ensure therefore that there are no chemicals, plastic parts, curtains or other textiles, etc.
EN 3. INSTALLATION NL This product may only be installed by a qualified electrical engineer. Important: FR In order to enable automatic system voltage recognition always connect the batteries before connecting the solar panels. DE 3.1 Location ES The product must be installed in a dry and well-ventilated area, as close as possible to but not above - the batteries. There should be a clear space of at least 10 cm around the product for cooling.
Table 1 below gives some examples of battery cable cross sections calculated with formula (5).
3.3 PV connection EN The PV input current of the charge controller is limited to 50A. In case of a potential solar array output exceeding 50A, the solar array voltage will increase up to the level at which the output is reduced to 50A. NL The voltage on the PV input should never exceed 150V under any condition. The charger will be permanently damaged if the input voltage is too high.

EN 3.4.4 Programmable relay The charge controller is equipped with a potential-free Single Pole Double Throw relay that by default is programmed according to option 3 below.
4. POWERING UP 4.1 Connecting the battery Close the connection to the battery, but DO NOT connect the solar array. All the icons of the display will now light up: This is followed by the software version: In this case the Software-version is 2.03 After the software-version has been displayed, the charger will start the system voltage recognition phase. The LCD-screen displays two values: Left: actual measured battery voltage.
4.3 Charge algorithm EN NL 4.3.1. Overview Several preset charge curves and one user adjustable curve are available, see table below. The DEFAULT-setting is algorithm nr 2. DE Absorption and max.
4.3.2. Procedure for choosing a preset charge algorithm a. Press SETUP during 3 seconds: the “Menu” icon will light up. b. Press the "-" or "+" button several times until the screen shows “ ”. c. Press SELECT: the algorithm number will now blink (a number with superscript “type”). d. Use the "-" or "+" button to choose the desired algorithm. e. Press SELECT to confirm the change, the value will stop blinking, and the change is made final. f.
EN If the absorption period is interrupted due to a cloud or due to a power hungry load, the absorption process will resume when absorption voltage is reached again later on the day, until the absorption period has been completed. NL The absorption period also ends when the output current of the solar charger drops to less than 2 Amps, not because of low solar array output but because the battery is fully charged (tail current cut off).

EN 4) Press SELECT: the text “” will blink, press SELECT again to erase the history data (kWh-counter, etc). Note that this takes a few seconds to complete. NL 5) Backlight automatic turn-off has the following options: OFF=backlight remains lit all the time, ON=the backlight will dim 60s after the last keypress, AUTO=when charging the backlight is lit, otherwise it will dim. FR Warning Some battery manufacturers do recommend a constant current equalization period, and others do not.
6. MANUAL EQUALISATION To allow the charger to equalise the battery properly, use the manual equalise option only during absorbtion and float periods, and when there is sufficient sunlight. To enable equalisation, enter the setup-menu and press the "-" or "+" button until the text “ ” is visible on the menu. Press SELECT: the text “” will blink, press SELECT again to start equalisation.
