RS485 DSP Control Hybrid Grid Inverter Lead Acid Lithium Battery MPPT

Hybrid PV Energy Storage Rack Mount Off Grid Solar Inverter

Product Instruction:

     HT series is a new hybrid PV energy storage inverter controller integrating PV energy storage, mains charging

and storage and AC sine wave output. Using DSP control through advanced control algorithms, it comes with high

response speed, high reliability, high industrialization standard and other characteristics. Four charging modes are

available: only PV, mains priority, PV priority, and hybrid charging by mains&PV; two output modes: inverter and

mains are available to meet different application needs. The PV charging module employs the latest optimized

MPPT technology to quickly track the maximum power point of the PV array in any environment and obtain the

maximum energy of the PV panel in real time.
     AC-DC charging module adopts advanced control algorithm to realize full digital voltage and current double

closed-loop control with high control precision and small size.

     The DC-AC inverter module based on a full digital intelligent design uses advanced SPWM technology to output

pure sine waves and convert DC to AC, suitable for AC loads such as household appliances, power tools, industrial

equipment, electronic audio and video equipment.
     With segmented LCD display design, the product can display the system running data and status in real time.

All-round electronic protections ensure that the entire system is safer and more stable.

     The figure below shows the system application scenario for this product, and a complete system consists of the

following parts:
1. PV module: converts light energy into DC energy to charge the battery through an all-in-one machine, or directly

changes to alternating current to power the load.
2. Mains or generator: connected at the AC input, to supply power to the load and charge the battery. If not connected

to the mains or a generator, the system can also operate normally, and at this time, the load is powered by the battery

and PV module.
3. Battery: The role of the battery is to ensure the normal use of the system loads when the solar energy is insufficient

and mains is not available.
4. Household load: It can be connected to various household and office loads, including refrigerators, lamps, TVs,

fans, air conditioners and other AC loads.
5. All-in-one inverter controller: energy conversion unit of the whole system.

Key Feature:

1. Full digital voltage; current double closed loop control, combined with advanced SPWM technology to output

pure sine wave.
2. Two output modes: mains bypass and inverter output enable uninterrupted power supply.
3. 4 charging modes are available for choice: only PV, mains priority, PV priority, and hybrid charging.
4. Advanced MPPT technology with efficiency up to 99.9%.
5. LCD screen design, with 3 LED indicators, for dynamic display of system data and run status.

6. ON/OFF rocker switch controls AC output.
7. Power saving mode reduces no-load loss.
8. Intelligent variable speed fan ensures efficient heat dissipation, and thereby extends system life.
9. Double lithium battery activation modes: mains and PV, and supports lead-acid battery and lithium battery

access.
10. Multiple protections provide 360 ° all-round protection for the system.

11. Complete protections include multi-electrical appliance air switch short circuit protection, overvoltage and

undervoltage protection, overload protection, back-flow protection, etc.
12. Horizontal installation facilitates cabinet combination installation.
13. Lithium battery can be activated by both mains and PV panel.
