1.Safety Summary
The following safety precautions should be taken to avoid injury and prevent damage to this
and other associated products. To avoid danger, be sure to use this product in accordance with the
instructions.
Before use, please read the user manual carefully. Operate the equipment according to
instructions.
The power input and output cables should comply with national standards, to avoid
accidental injury caused by inferior cables.
When disconnecting the power input cables, be sure that the power is off first!
When disconnecting the power output cable, be sure that the power is off first!
During operation, do not touch the power input or output cables. This is a shock hazard!
During operation, do not move the inverter!
Inadequate ventilation can cause the machine to overheat and to fail. Do not cover the
ventilation holes! Be sure that the area and inverter have proper ventilation.
Keep the product surface clean and dry. Do not drop small objects inside the machine.
In the event of a temporary power supply cut off, do not open the case to touch the inside
of the device until the capacitors discharge. There is still high voltage inside the machine.
The ground terminal must be grounded (Ground resistance less than 10 Ω). Use thick
diameter ground cable. Keep the ground cable short and as close to the machine as
possible.Ground is can be parallel.
2.Product Introduction
2.1 Introduction
The Helios Series Inverter consists of a Pure Sine Wave Inverter, MPPT Solar Charge
Controller and an AC Charger. The use of advanced components creates high reliability, high
efficiency, better protection and a cleaner waveform. Here are some other key features:
New soft-start circuit will reduce sparks created during cable connection
Inverter voltage output is programmable
Multiple machines can be wired in parallel for more power
New transfer switch seamlessly switches from grid power to solar power
Three inverters connected in series creates 3-phase power output
Energy metering with various protection functions.
4.3 inch TFT color screen makes operation more intuitive and user-friendly.
The Helios Series Inverter can power instruments, color TVs, satellite receivers, household
appliances, automotive equipment and more. The MPPT Solar Charge Controller can
intelligently control PV modules to efficiently charge the batteries. It is also compatible with
wind power.
