SAKO HYBRID INVERTER
I have successfully installed the SAKO inverter, and it is working very well with my solar setup. The inverter is easy to set up by following the instructions in the manual, and the manual confirms that it is a pure sine wave inverter. It works well with my 12V lithium battery and 600W solar panel. The unit I received is the E-Sun 1200W model with a 50A MPPT solar charge controller. The product label shows a maximum solar power of 800W, best PV range of 20–100VDC, operating PV range of 20–120VDC, and maximum solar open-circuit voltage of 120VDC. This matches my 600W solar panel well. One thing I really like is that it charges my battery very fast. The PV input connection uses MC4 connectors, which makes the solar panel connection neat and easy to disconnect when necessary. The cooling fan also works intelligently. It runs for a while, stops to minimize power usage, and starts again when needed. The screen light also goes off after a few minutes when no button is pressed, and it comes back on immediately when any button is pressed.
