All DC Power
YMGI Symphony SOLAR 86 Series
The all DC (86) Series is designed for use where AC electrical power is not available, and solar energy is the only available power source. Solar power is used to run the system, and excess generated power charges batteries that are used during overcast weather, or at night. YMGI’s (86) Series Solar HP compressor is powered by DC current. The (86) Solar heat pump uses DC power generated by the solar panels or stored in the batteries as needed. By using solar DC power instead of converting municipal AC power, YMGI’s (86) Series Solar HP can reduce daytime energy costs for air conditioning or heating by up to 100%.
On bright days, YMGI’s (86) Series Solar HP can get 100% of its power from three ≥ 300W solar panels. Up to six panels can be connected to the system increasing efficiency, and allowing it to run on 100% solar power even when weather conditions are partly cloudy or overcast. No power is exported by the system, so no special meter or net metering agreement is required.
The (86) system can be installed for hybrid operation by using an AC to DC Converter and municipal power. These installations have solar power providing the energy needed during daylight hours, supplemented by AC power at night or on overcast days.
YMGI (86) DC SOLAR Single Zone-Wall Mounted Indoor Unit
The installation of indoor units uses an integrated mounting plate and requires a 3” hole through the wall for conduit that houses all refrigerant pipes, electrical wiring and condensate drain hose. The wall unit has a motorized louver system that quietly distributes airflow evenly throughout the space.
YMGI (86)DC SOLO Single Zone-Outdoor Unit
With heating and cooling capacities of 09k, 12k, 18k, and 24k, the SOLO outdoor condensing unit is wired to a charge controller connected to a solar panel array and batteries. Depending on your installation configuration, you can achieve a SEER rating of up to 38. The SOLAR SOLO compact design allows for ground installation, or mounting in a variety of locations, including on a wall, under a deck or even on a balcony.
A Smart Heating And Cooling Solution
Mini-split systems are the easiest and simplest cooling solution for additions to existing homes, or older homes that have been built with non-ducted heating systems, like hot water heat, radiant heat or space heaters. They are a great solution for both new construction and retrofit or remodeling jobs. YMGI Symphony mini-split ductless air conditioning and heat pump systems are designed to heat and cool quickly, quietly and efficiently.
Mini-splits are ideal for room additions and newly enclosed spaces such as sunrooms, garages, sheds and pool houses that cannot be connected to the main central air conditioning system, or where extending or installing ductwork would be time consuming, costly, or even not possible.
How Mini-split Systems Work:
The Differences between Central Air and Mini-split Systems
All air conditioning systems consist of an outdoor condensing unit and an indoor evaporator unit. The basic difference between a mini-split and central system is that the evaporator unit of the central system is commonly installed in the basement or attic and uses metal or fiberglass ductwork to deliver warm or cool air to different rooms in your home. A central system requires space inside the walls between the joists for the ductwork, plus floor/wall/ ceiling space to install the registers. These systems are often noisy and the ductwork is a haven for dust, germs, mold, bacteria, and insects.
The mini-split system is totally ductless. The indoor unit is mounted in the room you want to heat or cool, so no ductwork is required. The outdoor and indoor units are connected with small refrigerant copper pipes and wires that are wrapped tightly and securely through a 3” opening in the wall. Installation is faster, and easier than a conventional ducted system.
The mini-split’s compressor (found in the outdoor condensing unit) pumps refrigerant through the condensing coils and the metering device to the indoor unit where a fan blows across the coil to cool the room.
In heat pump mode, the same unit absorbs heat from the outside air and moves it indoors to heat the room. For most climates, this results in efficient, heating and cooling, keeping you comfortable all year long.
The advantages of mini-split systems aren’t just on the inside. Most central system outdoor units are up-flow, which means the condenser fan is pointed upwards. Because of this, the outdoor units need more installation room. A mini-split system’s outdoor unit is horizontal flow, with the fan pointed sideways. Because it requires less room, a mini-split can be placed where installation of a central air system would not be possible. A mini-split can be installed on a concrete pad, a balcony or below a deck, making them ideal for metropolitan areas, where space between buildings can be very tight.
Maximum Comfort, Minimum Cost
A conventional forced air cooling or heating system uses an “on and off” cycle. When a conventional system starts running, it runs at its top speed, consuming the maximum amount of energy in order to reach the desired temperature. The system then has to cycle between on and off, in an effort to maintain the set temperature. The continual starting and stopping of the major components in a conventional air conditioning system reduces the life span of the compressor and other components.
YMGI’s mini-splits use a DC Inverter to convert alternating current (AC) to Direct Current (DC), modulate pulse width, and then direct the inverted current back to alternating current (AC) at the optimum frequency, giving precise control over the operating speeds of the electric motors and compressor. Our Symphony Series Mini-split DC Inverter system, allow your system to start slowly and smoothly, and then accelerate to higher speeds to quickly bring the room to the desired temperature. Once the set temperature is reached, the system slows and adjusts itself to counter the heat gain or loss of the building, maintaining a consistent temperature. Delivering maximum comfort at minimum cost.
Easy to Operate and Easy To Live With
Each YMGI mini-split indoor unit come with a remote control, that lets you select the operating thermal mode, fan speed, and oscillation of the air louvers, giving you total control of your environment. The remote also lets you program the start and stop time, and desired temperature. YMGI mini-split indoor units operate quietly, and have horizontal or vertical air directional louvers to evenly distribute conditioned air throughout the entire room. The outdoor units feature quiet operation, horizontal venting and a contemporary look.

It measures the temperature where people are located, not the wall or ceiling unit. Accurate temperature control for personal comfort.
YMGI Technology
- DC Inverter Technology – Continuously Adjusting for Profound Performance
Unlike conventional systems that cycle between on and off repeatedly, YMGI Symphony SOLO DC Inverter systems monitor room temperature and continuously adjust compressor speed up or down to provide precise temperature and humidity control. DC Inverter systems achieve this by converting alternating current (AC) to Direct Current (DC), modulating pulse width, and then directing the inverted current back to alternating current (AC) at the optimum frequency, precisely generating the thermal output needed, and maintaining the selected room temperature within very narrow ranges, while consuming substantially less energy. The incoming electrical power has a fixed frequency of 60 Hertz. By converter and inverter, the various current frequencies and voltages can be generated to supply the system, allowing the compressor to run at different speeds that suit the needs of various capacities and comfort levels with minimum energy consumption. - Optimized System Design
Components are both individually and systematically optimized to ensure SOLO and CHOIR systems work in wide ranges of applications, and deliver the right amount of heating or cooling when you need it, and with maximum efficiency. - Low Ambient Temperature Heating & Cooling
When outdoor temperatures reach low ranges, heat pump capacity and efficiency drop. In low ambient temperatures, YMGI’s DC Inverter technology operates better than many other systems available. The powerful heating system ensures you stay warm, even in extreme cold weather. YMGI’s DC Inverter technology and special control logic also make cooling in low ambient temperature ranges a reality. - Soft Start
The compressor starts at a lower voltage and frequency and accelerates, for a smooth and soft start. This reduces energy consumption of the outdoor unit by approximately 30% compared to conventional HVAC systems. This also reduces electrical circuit load when more than one electrical device is used. - Over-Current, Over-Heat & Over-Pressure Protection
Built-in protection for over-current, over-heat and over-pressure, ensuring safe operation and longevity of components and the unit. - Adaptive Smart Control
The adaptive smart control fuzzy logics enables responsive and precise control over the compressor frequency, voltage, fan speed and valve opening size. This ensures rapid, precise and safe adjustments; delivering the exact amount of warm or cool air with minimum energy consumption.
Comfort & Convenience
- Auto Mode
By continuously sensing and comparing the set temperature to the room temperature, this feature switches between heating and cooling modes automatically delivering the exact amount of warm or cool air needed to ensure maximum comfort. - Fast Turbo Heating and Cooling
This function boosts cooling or heating capacities at high compressor speed and fan speed. Rooms reach set temperatures as rapidly as possible. - Air Swing
Motorized louvers that pivot vertically or horizontally, direct air throughout a room, maintaining an even temperature, and eliminating hot or cold spots. The louver motor can also be turned off, so that you can direct air flow to a specific spot. And it can all be adjusted using the remote control. - Sleep Mode
With the Sleep Mode on, the system will adjust the room target temperature to slowly rise when cooling or fall when heating. Saving energy, and allowing you to sleep comfortably while preventing sudden changes in the room’s temperature. - On/Off Timer
Set your indoor unit to heat or cool any time of day. - Memory and Auto Restart
If your unit should lose power, YMGI remotes remember the operation mode, airflow, and temperature settings and continue normal operation once power is restored. - Self-Diagnosing
Error codes are shown either on the LED lights on the outdoor control boards. Should your system have a problem, it can be diagnosed easily and accurately by an HVAC professional, helping to quickly resolve the issue. - Digital Display On/Off
Our easy to read LCD display can be turned on or off with the remote control. This let’s you keep a room dark at night, or you can turn the digital display on and use the display as a night-light.
