Hey guys, we have a question! What constitutes a genuinely efficient setup for our hostel in the jungle @Feel Free? Panels, Controller, batteries, and converter?
We are hoping to capture and save enough energy per day to run (AC): a small chest freezer, a few AC outlets for a blender and charging small accessories, and power tools.
We are in the tropics, (8˚ lat, northwestern Colombia). We really want to buy local, as we know its available and here maintenance will be much easier with a guarantee; even if written by hand by the only tool seller in the village.
So if you could shed some light on what it is were looking for in order to run a smooth, simple and cheap system, it'd go much appreciated! Thanks!!!
I'll take a stab at it. A chest freezer in the tropics assume a kw hr a day, blender depending on how much you use it 300 watt hr to 1kw hr. Add another for lights and charging. 3 kw hr per day. Start with that so to be safe 1 kw of panels, an mppt charger an inverter and battery storage for approx 2 days of storage. Outback makes a marine rated inverter that would probably do well in a high humidity environment. Probably an outback marine mppt charger. You can probably go with a simple pwm charge controller if the array is close and money tight. Dc breaker boxes if you can get them or fuses if they are more common. Lots of South American battery makers so the heavy stuff source locally. Start with good equipment on the important stuff if you are remote as it won't leave you stranded. It's not much of an answer but it might trigger some responses.
