Features of High Frequency Inverter Controller

Power shortage solution: During the day: Use solar energy to the maximum extent possible to power the load equipment and charge the battery. (Energy saving)
At night: If there is no mains electricity, the battery energy is converted into AC power to supply the load. (Energy storage discharge)
All-in-one machine: PV or AC power supplies power to the load and charges the battery (energy storage) at the same time
PV & mains power supply to loads & charge batteries
Battery discharge (inversion)
Green Energy: High voltage PV input (120-450Vdc), high MPPT conversion efficiency (97%); traditional low voltage MPPT conversion efficiency is around 85%
Product power factor = 1.0, different from ordinary PF0.8 products, with stronger load capacity. 5KVA/5KW
PV wide range input (120-450V MPPT), maximum voltage 500V; customers are advised to install PV panels in series (300W 30V per panel, 12 panels in series are recommended). The series voltage is high and the current is low, so the PV wire used is also small, generally 12AWG. Due to the low current, the voltage drop through the wire is also low, resulting in low loss.
It can work without battery: any one, two or three input sources of PV/mains/battery can operate independently, which reduces installation cost.
Battery working alone: mainly used as backup when there is no mains power, no PV or insufficient PV.
PV working alone: mainly in remote areas without mains electricity, with low system cost requirements, PV provides lighting and other daily necessities during the day, and cannot be used as a backup
The mains power supply works alone, mainly in some areas with relatively superior mains power supply environment, but it is recommended to add batteries or PV, which can be used as backup or jointly carry loads to save electricity costs
Battery + PV Small off-grid household use, PV provides energy to the load during the day, and the excess energy is used to charge the battery. The battery discharges to provide energy at night
Mains + PV, to meet the needs of areas with good small power supply environment and high electricity costs, especially shopping malls, office areas, small convenience stores, etc. PV energy is sufficient to fully supply the load. If it is cloudy or rainy, the mains can supplement the insufficient power and save electricity costs.
Battery + AC power, similar to ordinary inverter, can be charged for backup use
Battery + Mains + PV, customers can refer to item 01 of the manual to set SOL priority. For details, see 01 Setting Analysis
It has intelligent battery equalization function (see the user manual for setting 30-36 for details), provides a voltage point higher than the normal floating voltage to activate the battery, fully charge (31.5V and 61.0V charging voltage), and provides a single equalization time (900 minutes maximum), equalization interval (0-90 range/day once). LCD has EQ flashing.
Inverter with pure sine wave output
The range of the mains input voltage can be chosen based on the needs of the load (personal computers and household appliances).
Using an LCD, battery charging current can be adjusted based on load needs.
An LCD display allows you to adjust the mains/solar priority input mode.
Suitable for both generator and mains input
Automatic restart function when mains is restored 7. Overload, high temperature, short circuit protection
A clever design for battery charging maximizes the battery's potential.
