Breakout board Solar MPPT charger LT3652

:idea: Breakout board MPPT (Maximum power point tracking) charger LT3652. With a breakout board users would be able to build robust chargers+battery packs that always will deliver. ( The only chargers that comes close is GoalZero and Genasun but both has severe limitations )

MPPT charger ( with function similar to a “Imax b6”…but simpler )

Charger fetures:

  • Solar panel ( (6v), 12v, 24v )

  • Thermoelectric generator

  • DC adapter 12v ( + step up in order to behave as a Solar panel…)

  • Programmable Charge Rate

  • Programmable Float Voltage Up Li-Ion/Polymer, LiFePO4, SLA, NiMH/NiCd Chemistries

Background:

If you expect to charge in cloudy days you sooner or later will prefer 12v at least 10-20watt. I measured 200mA from 21watt powerfilm (rollable) with a sky covered with clouds this summer in Sweden ( charging a GoalZero battery which seems to have MPPT alogrithm ) It’ would be nice with a charger ready for SERIOUS action … ( not just a toy )

I nice complement could be Thermoelectric generator combined with a wood gas stove

( copper rod through the stove connected to TEG )

I’m not alone take a look at candlepowerforums, modernoutpost

:idea: LT3652

with jumpers select float voltage and max charge current ( I believe in “keep it simple stupid” equals reliable )

  • MPPT

  • Input Voltage Range: 4.95V to 32V

  • Programmable Charge Rate Up to 2A

  • Resistor Programmable Float Voltage Up to 14.4V Accommodates Li-Ion/Polymer, LiFePO4, SLA, NiMH/NiCd Chemistries
