Single phase three phase 0.75kw 1.5kw 1hp 2hp 220v solar pump inverter
VEIKONG VFD500-PV solar pump inverter Features:
1. Cover voltage levels 220V AC and 380V AC.
Support single-phase 220V and three-phase 220V/380V pumps,the power from 0.4KW to 37KW.
2. Easy to use
The inverters automatically start or sleep only after being connected to solar battery panels without any parameter setting.
3. Highly reliable for using multiple protective measures
Including PV over-voltage protection,PV polarity reverse warning,and auto derating against over-temperture,which extend product life.
4. Use advanced MPPT algorithms,ensuring that the solar power tracking efficiency reaches 99%
5. Models of 2.2kW or lower can be configured with boost module,meeting low-voltage work requirements.This reduces the use of solar battery panels and therefore the cost.
6. it can implement auto switch between solar input and grid input by configuring the boost or auto switching cabinet(meeting lightning protection requirements),implementing 24-hour unattended work.

R&D test: test the hardware and software performance, to make the design more optimization, makes sure the products have excellent
performance before production;
Board test: test the performance of every board in our products, to reduce product defective rate;
IQC: take strict quality inspection for every income components, to ensure every income components are qualified.
Aging test: make the solar pump VFDs at run status, put them in the aging test house at 50°C for 48 hours, to remove every unqualified products.
Load test: the last and the most important test, add different load to the solar pump VFDs, test their input and output value, to check their
working performance. unqualified products will be removed from the team.
By applying such strict testing process, VEIKONG ensures every outgoing solar pump VFD has excellent quality.
For 220V single phase motor connection
1: Single phase asynchronous motor wiring method (without starting capacitor):
Notice: U is connected to the common end of the starting winding and the working winding, V is connected to the starting winding, and W is connected to the working winding;
Single-phase asynchronous motor if the rotary steering is not correct, you can change the V and W wiring or set P22.13=1.
First solution: Set parameter P11.01=1 (Single phase motor type without capacitor) or second solution: set P00.11=31 if your motor frequency is 50 hz or set P00.11=32 if your motor frequency is 60HZ
For 220V single phase motor connection
2: Single-phase asynchronous motor wiring method (with capacitor)
Notice1: First solution: Connect motor cable to power terminal U and V and enter BSC mode to Set parameter P23.15=0(output phase loss shielding protection) or second solution: set macro P00.11=21 if your motor frequency is 50HZ or set P00.11=22 if your motor frequency is 60HZ
