pump inveter
the biggest Optical power tracking,Light weak auto
sleep,Light intensity automatically wake up,High water
level automatic stop,Low water level automatic run,under
load protection.
Peronalization function
Self-inspection
of peripherals
after power-on
After powering on, peripheral equipment will perform
safety testing, such as ground, short circuit, etc.
Common DC bus
function
Multiple inverters can use a common DC bus.
Quick current
limiting
The current limiting algorithm is used to reduce the inverter
overcurrent probability, and improve whole unit anti-
interference capability.
