Cool. I designed a 8x8 foot freezer using parts from a chest freezer. Have not built it, someone else was interested. Wife doesn't like my projects, so have stayed away from building much beyond a whole house UPS to keep essentials going for couple days.
MPPT is maximum power point transfer. Electronics to match a solar panels output to a battery. Solar panes are rated at some ideal voltage and current to make rating of panel. Example for a 34 watt panels is17v at 2 amps. (easy numbers) If connected directly to 12v battery, you get 13x2 or 26w of usable power. Much less than the rating of the solar panel. MPPT controller will boost usable power up to maybe 32watts. Depending on you planetary location the benefits of MPPT can vary just like a tracker. Here in MI, claim is around 25% boost in power using MPPT and 29% tracking. Both if done DIY are cost effective, cost determines whether its worth doing.
Have fun, Scott. [ Parent ]
If I would be better served by posting this question in the wind section, I'll ask over there instead. Thanks.[ Parent ]
