This is the Sunny Buddy, a maximum power point tracking (MPPT) solar charger for single-cell LiPo batteries. This MPPT solar charger provide you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargable LiPo battery. Set-up is easy as well, just plug your solar panel into one side of the Sunny Buddy and your battery into the other and you are good to start charging!

The output of the Sunny Buddy is intended to charge a single polymer lithium ion cell. The load should be connected in parallel with the battery. By default, the Sunny Buddy comes set to a maximum charge current of 450mA with a maximum recommended input of 20V (minimum 6V). It’s recommended that batteries not be charged at greater than their capacity rating; thus, the smallest battery that should be charged with the Sunny Buddy is 450mAh.

Each Sunny Buddy comes equipped with a LT3652 power tracking 2A battery charging circuit and pre-installed barrel jack and 2-pin JST connectors with unpopulated areas to install your own personal 3.5mm screw terminals for added input/output options. This revision also adds a potentiometer to the input to set the holding voltage for MPPT and we’ve also tweeked the feedback resistors on the output to change the float voltage.

這是陽光好友,最大功率點跟踪(MPPT)太陽能充電器單節鋰聚合物電池。這MPPT的太陽能充電器為您提供獲得最大可能的功率輸出的太陽能電池板或其他光伏裝置,並成為一個可充電鋰聚合物電池的能力。建立方便為好,只需要插入您的太陽能電池板到陽光好友和你的電池到另一個的一側,你是好開始充電!

在Sunny好友的輸出旨在單一聚合物鋰離子電池進行充電。負載應連接在與電池並聯連接。默認情況下,陽光好友自帶設置與20V(最小6V)的最大推薦的輸入450毫安的最大充電電流。它的建議,電池不超過其額定容量越大充電;因此,應被控陽光好友最小的電池是450mAh。

每個陽光巴迪配備了一個LT3652功率跟踪2A電池充電電路和預裝桶插孔和2針JST連接器無人區安裝自己的個人3.5毫米螺絲端子以增加輸入/輸出選項。本次修訂還增加了一個電位器的輸入來設置MPPT保持電壓並且我們也tweeked輸出上的反饋電阻來改變浮充電壓。
