Solar Charge Controller China

MT1550-EU is a sort of MPPT solar controller 12v.

15a solar charge controller，named MT1550-EU，means 12V system voltage, as well as 15A charge and discharge current.

MT1550-EU is the latest solar controller 12v in the Magic Series. It is a sort of small MPPT controller that Very suitable for boats.

Normally there are many kinds of PV panels, from 10W 20W … to 320W, but you can divide the panels to two kinds: off-grid and on-grid. You can divide according to the cells number, like 36 pcs cells and 72 pcs cells can be used in off-grid systems, 60 cells can be used for on-grid systems. Boats need battery as back up energy supply, normally small panels are suitable, so the off-grid PV panels are widely applied in boats.

Why do people build solar system on boats? First, in winter time, nobody like to go out in cold weather, but the battery self consumption is serious, need to start up the engine to charge the battery routinely, like one time in a month or two month. If you don’t start up the engine to charge the battery, then the battery will be out of power, then you can’t start up the engine, and  the life span of the battery will be shorten easily.  Second, if owners like to use some appliance on the boats, then they can build one solar system to get the energy, since the solar energy is clean and cheaper than gasoline.

Normally, the owners like to use one small PV panels on the boats. For 36 pcs cells panel, the biggest power will reach to about 190W, then our MT1550 can connect with 200W power, is very suitable for the panel. MPPT can improve about 20% charging current when battery voltage is low. So MT1550 can cover all kinds of single off-grid panel, which is very suitable.

MT1550 has one LCD with many information inside, which is easy to understand by the end users, like the charging voltage and current of the PV panel/battery/load, how many AH energy is generated by the system, how much energy is left in the battery? Some warning information about the system, and you can adjust some parameter use the button according the information on the LCD. Also MT1550 MPPT solar charge controller has some protection function, like over temperature protection, load short circuit protection, battery reverse polarity protection… which can protect the wrong operation damage well.

Also MT1550 has very competitive price, very high tracking efficiency and conversion efficiency. It is deserved to buy some small MPPT controllers for your boats.
