First point, FTS-502 solar inverter overview
1.This solar inverter is the core equipment of distributed photovoltaic (PV) power generation system, specially designed to efficiently convert the direct current (DC) generated by solar panels into alternating current (AC). This power level is particularly suitable for:
(1) small and medium-sized household PV systems
(2)Small commercial premises
(3)Energy storage systems
2.Basic parameters
(1)Rated power: 5KW
(2)Input voltage: DC 24/48V, AC 165-275V 50/60HZ
(3)Output voltage: 220V 50/60HZ
(4)Support solar array:
Maximum open circuit voltage ------150VDC
Maximum power ------------1700w(24v)/34000w(48v)
(5)Charging current: DC 60A MPPT ,AC 34A

The second point, the core technology and performance characteristics
1. STABLE AND DURABLE
Built-in toroidal transformer, peak power up to 3 times the rated power, effective and stable output, solid and durable.

2.Intelligent control
Five intelligent control modes are convenient for customers to choose according to site requirements.
(1) AC Utility Priority Mode: The loads will be prioritized to use the grid utility, and when the AC utility is disconnected, the power will be supplied by the battery.
(2) DC Battery Priority Mode: The loads are prioritized to use the battery power, and when the battery power is insufficient, it will be automatically replaced by other power supply, such as utility power or solar power.
(3) ECO Mode: Conventional inverters run continuously and consume a certain amount of power even when they are unloaded. In this mode, when the system detects that the load is less than 10% of the rated power, the system goes into standby mode, thus saving energy.
(4) Generator Mode: When a generator is used as the primary backup power source, selecting this mode allows the system to start the generator to supply power.
(5) Unattended Mode: This mode allows the system to automatically handle power switching, fault recovery, and energy management without human intervention, and is suitable for scenarios that require continuous and stable operation but cannot be monitored in real time.
3,MPPT charge controller
Traditional system (without MPPT) may lose more than 30% of energy due to impedance mismatch, while MPPT can reduce the loss to less than 5%.MPPT can adapt to complex environmental changes, quickly respond to changes in light intensity, such as cloud movement, sunrise and sunset, to reduce the loss of efficiency brought about by power fluctuations.
