has anybody tried this one
https://www.ebay.com/itm/5A-MPPT-So...-LiFePO4-Battery-Charging-Board/283982202592?
Features:
1.100% Brand New and High Quality
2.MPPT Technology --- 5A solar maximum power point tracking
3.High efficiency synchronous rectification step-down charge management, the highest efficiency up to 96%
4.Solar cell maximum power point tracking (MPPT)
5.Solar cell maximum power point tracking (MPPT) is to ensure that in the light intensity changes, photovoltaic cells have been the maximum output power to make full se of solar energy. Under normal circumstances, need to use the switch mode DC-DC converter MPPT function, to maintain the output voltage and charge current product (output power) to maximize.
6.The switching step-down synchronous rectification DC-DC conversion of photovoltaic cells to achieve the maximum power point tracking function, the input voltage up to 28V, very suitable for the input voltage and battery voltage difference between the larger applications.
now i expect very little out this and i am still waiting for it , i have a 50 watt panel left over from a old project , do not really care if i only get 3 amps of power as long as it will not hurt my lfepo4 battery just doing it for fun lets see i have a 200ah battery 3 amps 66 hours to fully charge figure 5 hours a day average so about 14 days to recharge ,
adding this to my my furnace back up
next year i hope to add real solar panel and controller to it
