![]() ![]() You are, this is the right system for you. Solar powered heating, operating all the way down to an outsideĪmbient temperature of 5 ⁰F. In addition to cooling, the ACDC12C solar heat pump will provide With up to 100% of the energy coming from sunlight. Note, the maximun total voltage of a panel string can never be >325v open circuitrating.įor home or office use, this system can cool an area for free If using 60-cell panels, the above panel recommendations can be +1 or +2. We also have an ACDC18C that works in a similar manner and should have 4x 72 cell panels >/=400w panels for normal grid connected use, and 6 connected 72-cell panels when used without grid power. The ACDC12C includes a digital power display so you can get an idea of how much AC and/or DC power is being used in the system. Of course, the unit will not run without an AC connection in low sunlight conditions, or at night. Note, a 144 "half cell" panel is essentially the same as a 72 cell panel. The brownout/cycling buffer can be as high as, or more than, 50%, so for a fully offgrid application we suggest 6x 72-cell panels 400w or larger as being optimal. If no AC connection is available, the ACDC12C estimates the amount of solar power available in real time based on panel voltage and reduces its speed to match the estimated amount of available solar power, less a buffer to prevent brownout or frequent cycling on/off. When a grid connection is present, the ACDC12C can use all of the available solar power before using any contribution from the grid and should have 3x 72-cell solar panels of 400w or larger. ![]() Normal AC power, if available, at times when solar availability is reduced due to clouds, overcast sky, or at night. Primarily uses solar power, and mixes it with Hybrid operation eliminates the need for batteriesĪnd allows use of the system 24 hours per day. Uses small amounts of power from the utility company, if andĪs needed. When connected to both solar and an optional AC power source, the ACDC12C only Color adjusted for photo contrast, indoor unit is white. Second image shows AC power connected, unit running at low speed on DC/solar power. Shown in heating mode, 90 ⁰F setting.įirst image shows a unit using all DC/solar power with no AC power connected. Displays at right are built into the indoor unit and visible only when the unit is on. During the day it can operate on 100% solar power. But unlike previous versions, the ACDC12C does not require an AC backup connection to operate during good sunlight conditions. Like our previous solar hybrid versions, the ACDC12, and ACDC12B, the ACDC12C blends solar DC power directly with AC power to deliver a seamless cooling or heating experience while making the best use of free DC solar power. We are pleased to offer our 5th generation solar AC, the model ACDC12C. The HotSpot engineering team created the world's first DC solar air conditioner in 2007 and has led the world in solar AC design and quality manufacturing for more than 10 years. If also connected to AC power source, the unit can run at full speed whenever needed, and will add in just enough AC power, if/as needed, while still primarily using available solar DC power. The maximum speed/capacity will be based on the level of available solar power available. See ACDC12C Spec Sheetĭuring the day the ACDC12C can run exclusively on solar power with no AC power or grid connection when solar is strong enough. A grid connection can be added to automatically allow operation at night, as well as to provide higher daytime capacity & uninterrupted operation during cloudy or low sunlight conditions. Plug in the solar panels and start saving up to 100% on daytime cooling or heating costs. ![]() Like previous versions, it also needs no batteries, no inverter, no charge controller - just This is the 5th generation of our ACDC12x solar air conditioner series with a new key feature we've had so many requests for - our new "C" model ACDC12C solar air conditioning technology SAVE Up To 100% ON COOLING / HEATING COSTS Solar Air Conditioner / Solar Heating (AC-DC) Heat Recovery Water Heating & Pool Heating DC Solar Air Conditioner Heat Pump | Solar Air Conditioning | Solar Heating | Manufacturers ![]()
