(56) Solar PV Assisted DC Inverter Mini Split
Solar Assisted Single-Zone Wall-Mounted Mini-split
Solar Assisted Heating & Cooling
When the sun is shining, that’s when you need your air conditioner the most. The (56) can be installed where AC electrical power is available, but the customer wants to utilize solar energy during the day to lower cooling and heating costs, without worrying about unit usage when it’s cloudy or dark. With cooling capacities of 9k,12k, 18k, 24k, 30k, and 36k these single zone systems require 208-230 volt, 1 phase, 60Hz municipal power supply. Municipal power allows the system to run consistently when the weather is overcast, or during night time operation.
The (56) SOLAR can be wired directly to an array of solar panels to offset power consumption. Depending on your installation configuration, you can achieve a SEER rating of up to 35. The system can also be wired to a charge controller and battery bank, that will store solar power not used by the system, and run the system for up to 4 hours.
No power is exported by the system, so no net metering agreement or special meter is required. The system can seamlessly utilize both power sources, with a bias towards using all available DC (solar) power. 1198 models require solar panel voltages of 250-400 VDC. Solar Panel voltages less than 250VDC will not offset municipal power usage. A transformer is available to allow usage of lower voltages.
Heat and cool your home or office with reduced energy costs. Keep daytime temperature rise or loss to a minimum, and help reduce evening heating and cooling costs. Attached to municipal power supply, the high efficiency system will save money while keeping you comfortable, even when the sun isn’t shining. Designed to use much less electricity than a central air conditioner or heat pump of the same capacity.

A Smart Heating And Cooling Solution
YMGI Symphony mini-split ductless air conditioning and heat pump systems are designed to heat and cool quickly, quietly and efficiently. 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.
Mini-splits are a great choice for room additions and other structures such as sun rooms, garages, sheds and pool houses. Heat and cool rooms and structures that cannot be connected to the existing central air conditioning system, or where extending or installing duct work would be time consuming, costly, or impossible.
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 duct work to deliver warm or cool air to each room in your home. A central system requires space inside the walls between the joists for the duct work, plus floor/wall/ ceiling space to install the registers. The duct work can be a haven for dust, germs, mold, bacteria, and insects.
With a mini-split system, the indoor unit is mounted in the room you want to heat or cool. The outdoor and indoor units are connected with copper refrigerant pipes, and power and communication wires, that are wrapped tightly, insulated, and passed through a small 3” opening in the wall. Installation is fast and easy.
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 heating mode, the unit absorbs heat from the outside air and moves it indoors to heat the room. In most climates, this provides 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, so 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 cycles on and of 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 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 room, maintaining a more consistent temperature. Delivering maximum comfort at minimum cost.
Easy to Operate and Easy To Live With
Every YMGI mini-split indoor unit comes with a remote control, that lets you select the thermal mode, desired temperature, fan speed, and oscillation of the air louvers, allowing you to customize your comfort. The remote lets you program the start and stop time. YMGI mini-split indoor units use oscillating louvers to evenly distribute conditioned air throughout an entire room. The outdoor units feature quiet operation, horizontal venting and take up less space then a conventional central air condenser.

YMGI Technology
- DC Inverter Technology – Continuously Adjusting for Profound Performance
Unlike conventional systems that repeatedly cycle between on and off, YMGI Symphony SOLO DC Inverter systems monitor room temperature and continuously adjust compressor speed up or down to provide precise temperature and humidity control. The incoming electrical power has a fixed frequency of 60 Hertz. DC Inverter systems convert alternating current (AC) to Direct Current (DC), modulate the pulse width, and then convert the inverted current back to alternating current (AC) at the optimum voltage and frequency, allowing the system precisely generate the temperature needed, and maintaining room temperature within a very narrow range, while consuming substantially less energy. - Optimized System Design
Components are both individually and systematically optimized to ensure SOLO 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 drop, heat pump capacity and efficiency are lower. In low ambient temperatures, YMGI’s systems operate at higher efficiency than many other systems on the market. 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, ensure safe operation and component longevity. - Adaptive Smart Control
The adaptive smart control fuzzy logic 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. - Super Heating and Cooling
This function boosts cooling or heating capacities at high compressor speed and fan speed. Rooms reach set temperatures as quickly 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. This saves energy and allows you to sleep comfortably while preventing drastic changes in your room’s temperature. - 24-Hour 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 systems 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 LCD display of the indoor unit, or LED lights on the outdoor control boards. If your system experiences an issue, it can be diagnosed easily and accurately by an HVAC professional, and help 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.
