Standard Inverter has 20% conversion loss and almost 48% static loss .Along with 10% loss from solar charge controller a complete standard Solar system has to suffer a total of 75% energy loss. Effective sun hour in most places is 4 and half hour. So to charge batteries in this limited time and to gain 3-4 hour back up the standard solar system requires more than twice solar panel than operating load. For example to compensate the heavy system loss of traditional inverter 1 KW load needs 2KWp panel.The loads that are used generally are 40 watt Fluorescent tubes,CFL bulbs, 80 watt standard fans and others. All of them requires high power to run.
On the other hand ESS uses micro inverter with zero static loss and 93 % efficiency. with only 12% system loss ESS does not need excess panel to support long (4-12 hour) back up. The appliance in ESS are highly energy efficient. Power consumption is 75% less than conventional appliances.as a whole ESS replaces 1000 Watt load with 300 watt(equal performance) , 2000Wp panel with only 300wp while extending backup time upto 12 hours.

Q. ESS solar charge controller charging voltage?
ESS charge controller voltage is 24,48 volt
Q. What is sun hour?
In simpler words it’s the effective hours that the solar panels gets to harness energy from the sun
Q. What is the sun hour in south asian region?
It is arround 4 to 4 and 1/2 hours
