20A 12V 24V 48V MPPT-20 JUTA MPPT Solar Controller
20A 12V 24V 48V JUTA MPPT Solar Charge Controllers Regulators
1. MPPT Solar Controller Benefit
MPPT (Maximum Power Point Tracking) controller is a new generation of solar products. The most outstanding feature of this controller is intelligent tracking input voltage from solar panel, which could let solar panel always working at Maximum Power Point of V-A curve. Compared with normal solar charge controller, this MPPT controller could increase 10%-30% electrical power using efficiency from solar panel.
2. MPPT Solar Controller Function:
This MPPT controller is not only having above mentioned special function, at the same time including completely protecting and controlling functions:
-Overcharge protection
-Over-discharge protection
-Battery Reverse Current Protection
-Overloading Protection
-Short Circuit Protection
-Reverse Polarity Connection Protection
3. Form a complete set:
Solar Panel: 12V solar system should use 40PCS cells laminated solar panel. The maximum power point voltage is 18V above. 24V solar system should use 2PCS above mentioned solar panels. 48V solar system should use 4PCS above mentioned solar panels.
Conductor: The cable between solar panel with MPPT solar charge controller should be better calculated by 1Ampere per 1mm² .
Solar Charge Controller: JUTA brand MPPT-10 Model solar charge controller Rated input Ampere is 10A. We have 12V, 24V and 48V three kinds of MPPT solar charge controllers (other specifications could be designed as customer special request). Fit for power of solar panels: 20_200Wp (12V), 40_400Wp (24V), 80-800Wp (48V).
4. Simply Measure Method:
For 12V system, measure the input voltage from solar panel with multimeter (terminal 1, 2 of controller), it is normal if the voltage of solar panel more than battery voltage 0.5-6V. Generally, the higher input voltage, the better charge efficiency. For 24v and 48V system, the input voltage will be much higher than battery voltage
(Note: It is normal the controller can not find Maximum Power Point within 10 minutes from system start. )

My solar system voltage output is 98.5 volts. 4×80 watt panels,connected in series. Is this voltage compatable for a Juta mppt 20A controller. Or should they be connected in parrellel to get about 18 volts
