Digital Controlled PWM technology based Solar Charge Controller & Regulator of 6.4V-6amps with inbuilt protections and 6V battery charging feature for LiFePo4, Lithium Ion and Lead Acid type batteries of upto 6.4V. Specially designed for recharging LiFePo4 and Li-Ion batteries that should not be charged by normal solar charge controllers used for lead acid type 6V batteries as it can damage the battery permanently by under charging, voltage differences that may ultimately reduce the cycles of the battery. It can be connected to a maximum of 20W solar panel with VOC of upto 9V and a battery bank of 6.4V. The controller features a smart tracking algorithm that maximizes the energy harvest from the PV and also provides load control to prevent over discharge of the battery There are a number of protections that the Solar Charge Controller ensures. Solar Charger Controller stops reverse current flow from battery to solar array, it provides load short circuit protection, it provides Battery/Panel reverse protection through DC fuse and Overload protection also. Additionally it has a 5V USB which is suitable for recharging smartphones & other 5V devices
