XTRA Series  MPPT solar charge controller

XTRA series are advanced maximum power point tracking (MPPT) charge controllers, for off-grid photovoltaic systems, with optional display units (XDB1/XDS1/XDS2).In order to maximize the energy harvest from PV arrays and simultaneously minimize the power loss within a wide range of operating conditions, the XTRA series apply an advanced smart algorithm which results in up to 30% higher efficient charging, compared to a conventional pulse width modulation (PWM) charge controller. Xtra series controller has a limit protection function on charging current &charging power, as well as auto derating power operation at high temperature; the above protection ensures the stability of the system even at exceeded rated PV power and over-temperature conditions. Protection class IP32 and isolated RS485 communication port further improve the controller's reliability under dierent application requirements.XTRA series controllers incorporate a self-adaptive three-stage charging algorithm based on a digital control circuit, which effectively prolongs the lifespan of the battery and significantly improves the system performance. It also has extensive electronic protection for overcharge, over-discharge, PV&battery reverse polarity and etc. to ensure the sustainability and durability of the o-grid solar system.

Thank you. The package arrived in excellent condition. This solar controller works great, better than the PWM controller I used before and I love that it displays information in real time. Excellent product.

The controller is excellent, but who has a micro solar station keep in mind that at small current input it works at a loss, where then with a 950ma works one to one. Most importantly shows the entrance from the panels ostensibly 300 Ma, and output 400, actually vice versa-input 400, and output 300mA, but after one ampere the readings are very, to say that the controller is bad, the controller is perfect, brand, and works on normal panels well, If you need a controller for a mini station, take here the same win500 MPPT-super controller, works with small currents, probably put it back. And this one's great anyway.
