🟢 Solar DC PV2L Home Heating Playlist - • Solar PV Electric Heat... I have been heating my home for a while now using converted space heaters that run straight off of solar panels and DC. In this video I address some of the safety concerns in running my converted space heaters directly off of DC Solar Photovoltaic power. AC heaters are unsafe to run off of DC without proper considerations and modifications. I will explain some of the differences in AC and DC, and how this impacts design and engineering choices during the conversion process.

My DIY heaters use LOW VOLTAGE DC in the ~30-50V range, not high voltage. Therefore electrocution hazards are greatly reduced. But even 48V will "zap" a person and so should be handled with care and respect.
Converting an AC space heater to DC operation in the 30-50Vdc region requires a certain level of care and understanding to avoid accidental fires during operation. AC heaters were never intended to handle DC inputs. The switches and devices inside can fail when switching Direct Current. This video is part 3 in a series which documents my conversion of AC heaters to low voltage DC, and addresses the need for a straightforward non-electronic solution to over temperature, tip over and power on/off controls.
In the past I have also used car/truck cab heaters and PTC (positive temperature coefficient) heating elements to heat my home directly off of solar panels. But I eventually standardized on converted AC space heaters, because they don't need a fan usually. I now have over 8 converted heaters of various types running successfully off my solar panel arrays.
This method of heating straight off solar panels has an efficiency all of its own: the ability to heat your home with just 2 small skinny wires. Although solar thermal produces more heat, it is also far more complex, and can't cool your home in the summer like solar panels can. Therefore I choose to use my excess solar panels for home heating without any hesitation. Why let underutilized solar panels get old in the sun, after the batteries are full they can heat your home too.

Welcome to the Solar Power Edge Channel - I am doing research into Solar PV electric heating concepts including PV-To-Load (PV2L) solar electric space heaters. My channel has a collection of videos I recorded about my various projects. For example, heating a home or shop with solar power directly using simple and robust heater designs. PV-to-Load is one of the many technical terms used to describe the operation of an electrical appliance directly from Photovoltaic Solar Panel arrays. Examples include heating loads, cooling, irrigation and so forth.
For a few years now I have been using DC PV Solar powered heaters of various types (car or truck cab heaters, Positive Temperature Coefficient or PTC and Quartz Infrared) to successfully heat my home and shop. My favorite heaters are the AC space heaters I converted to low voltage DC operation: they work extremely well but require significant modification to use safely. No batteries, inverters or high voltages are used in my heaters.
This concept has its own efficiency and advantages versus solar-thermal, such as simplicity, low cost, flexibility for use outside the heating season and the ability to heat a space through a couple of thin wires.
