Product Description:

Off-Grid Solar Inverter 3KW-8KW    

 

EA-GF series products are on the basis of green energy use and equipment electricity need for remote area, combing the electricity characteristics of household appliances, communication station equipment and computer peripheral equipment. They have the function of energy conservation and environment protection. They adopt MCU control technique, having various kinds of function such as multi-setting mode, MPPT control, voltage stabilization on line, short-circuit protection, inverter frequency adaptive, output overload, battery charging management, monitoring etc. With display of LCD and LED, all the parameters and running status could be visible. Intelligent monitor is available via RS232 &USB connecting with PC, while remote control via RS485 &SNMP. EA-GF series products are the ideal power supply delivered with excellent performance, high stability, high reliability and high practical applicability

·         Q. What is an UPS and What it is for ?

An uninterruptible power supply (UPS) is a device that allows your computer or telephone switch or critical equipement to keep running for at least a short time or longer time when the primary power source is lost. It also provides protection from power surges, spikes, brownouts, interference and other unwanted problems on the supported equipment.

·         Q. How long the UPS to run when power goes?

This can take 3 paths.
1.You can pick a UPS that is rated for pretty much the full VA you need so it will be running at 100% of capability and will thus last 'n' minutes.
2.You can pick a UPS that is rated at a much higher VA value than you really need so, for example, is running at 50% of capability and will thus last for longer than the UPS from option 1.
3You can use extra external battery packs to run for longer. If charging capability allows, the more and the bigger batteries you take with, the longer time UPS runs. 
or using a generator after about 6 hours, it will be more cost-effective, with a short runtime UPS to bridge the generator start-up gap.
