Great Unit, Fast Delivery. All functions work, e.g Will switch off, then back on when the Sun comes up without intervention, With any 24V Inverter NOT used for critical heart oxygen pumps etc,, turn 'Restart on Overload' OFF always, you might not be around to correct the overload, auto restart actually loops 'off on, off on, off on' pounding the battery into the ground flat, dead flat. Fridges get compressor lock, Pumps inrush AC' No BMS cable to inverter in the 24V world, LiFePO4 26.5v, use 24.0 Volts for Low DC Cutoff! yes 24.0. Smallish Terminals' so your work must be PERFECT when you wire it in, get Ferules! real cheap. Recheck terminal tightness four times after any movement. Don't run any brand of Inverter on Max output for more than five minutes tops, otherwise Short Life, unreliable' use 50% head room rule, any brand, need 3KW ? Buy 6KW.

The purchase took place on August 8, 2024, I bought an inverter and two batteries.
On August 16, 2024, I received three tracking numbers - one for the inverter and one for each battery.
Delivery was carried out by the Mees Express carrier ABSOLUTELY WITHOUT CUSTOMS DUTY.
The first parcel was an inverter, it was delivered to Ukraine, Kyiv, in 16 days by air.
Two other parcels were delivered to Ukraine, Kiev, in 73 days by sea.
Everything arrived without damage, fully functional, the batteries were 13.15V each.

The inverter is a bit noisy for installation in a living space, it is recommended to install it in a technical room, such as an attic, basement or garage.
