BlueSolar MPPT 75/10 solar charge controller

<h2>Ultra-fast Maximum Power Point Tracking (MPPT).</h2> <p>Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM (pulse width modulation) charge controllers and by up to 10% compared to slower MPPT controllers.</p> <h2>Load output</h2> <p>Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage.</p> <p>Alternatively, an intelligent battery management algorithm can be chosen: see BatteryLife.</p> <p>The load output is short circuit proof.</p> <p>Some loads (especially inverters) can best be connected directly to the battery, and the inverter remote control to the load output. A special interface cable may be needed, please feel free to consult the manual.</p> <h2>BatteryLife: intelligent battery management</h2> <p>When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a “partially charged” state and the “end of discharge” state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months.</p> <p>The BatteryLife algorithm will monitor the state of charge of the battery, and if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly 100% capacity. From then onwards the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.</p> <h2>Programmable battery charge algorithm</h2> <p>See the Support & Downloads > Software section on our website for details.</p> <h2>Day/night timing and light dimming option</h2> <p>See the Support & Downloads > Software section on our website for details.</p> <h2>Real-time data display and history options, programming</h2> <p>- ColorControl GX or other GX devices: see the Venus documents on our website.</p> <p>- A smartphone or other Bluetooth-enabled device: VE.Direct Bluetooth Smart dongle needed.</p> <h2>Technical details:</h2> <p></p> <table> <tbody><tr><td>BlueSolar charge controller</td> <td>MPPT 75/10</td> <td>MPPT 75/15</td> <td>MPPT 100/15</td> <td>MPPT 100/20</td> </tr><tr><td>Battery voltage (auto select)</td> <td>12 / 24 V</td> <td>12 / 24 / 48 V</td> </tr><tr><td>Rated charge current</td> <td>10 A</td> <td>15 A</td> <td>15 A</td> <td>20 A</td> </tr><tr><td>Nominal PV power, 12 V 1a, b)</td> <td>145 W</td> <td>220 W</td> <td>220 W</td> <td>290W</td> </tr><tr><td>Nominal PV power, 24 V 1a, b)</td> <td>290 W</td> <td>440 W</td> <td>440 W</td> <td>580W</td> </tr><tr><td>Nominal PV power, 48 V 1a, b)</td> <td>n.a.</td> <td>n.a.</td> <td>n.a.</td> <td>1160 W</td> </tr><tr><td>Max.
