{"product_id":"sparkfun-sunny-buddy-mppt-solar-charger","title":"SparkFun Sunny Buddy - MPPT Solar Charger","description":"\u003cp\u003eThis 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!\u003c\/p\u003e \u003cp\u003eThe 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.\u003c\/p\u003e \u003cp\u003eEach 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.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/datasheets\/Prototyping\/SunnyBuddy-v13a.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/datasheets\/Prototyping\/SunnyBuddy-v13.zip\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\n\u003ca href=\"http:\/\/cdn.sparkfun.com\/datasheets\/Prototyping\/LT3652.pdf\"\u003eDatasheet\u003c\/a\u003e (LT3652)\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sunny-buddy-solar-charger-v13-hookup-guide-\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/weather-station-wirelessly-connected-to-wunderground\"\u003eWeather Station Tutorial\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\n\u003ca href=\"https:\/\/github.com\/sparkfun\/SunnyBuddy\/tree\/v13\"\u003eGitHub\u003c\/a\u003e (Design Files)\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40331918377045,"sku":"12885:PRT-12885:spark","price":4325.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/12885-01.jpg?v=1663613579","url":"https:\/\/www.tanotis.com\/products\/sparkfun-sunny-buddy-mppt-solar-charger","provider":"Tanotis","version":"1.0","type":"link"}
