Efficiency , durability and Cost are some of the factors one needs to consider when chosing batteries for your inverter system.
Lead acid batteries are the cheapest and well within the reach of most people compared to lithium ion batteries whose cost is more than double.
Most manufacturers will give warranty of 1-2 yrs for lead acid battery compared to 2-5yrs lithium battery.
A lithium ion battery DOD (depth of discharge) is between 80-99%. Meaning, it can discharge all of its energy when in use compared to lead acid battery whose DoD is usually around 50%.
A 250ah lead acid battery can only give out about 125ah compared to lithium batteries of that same capacity that can discharge from 200-248ah.
Efficient battery management. In terms of the aforementioned, lithium ion technology does a good job managing a large bank of battery compared to lead acid.
I'm summary, cost seems to be the only advantage lead acid battery ( gel, flooded etc) seems to have over lithium ion battery

UTP cable is certainly the most popular type of network cable by far around the world. UTP cable is used not only for networking, but also for the traditional telephone (UTP-CAT1). There are six different types of UTP categories and, depending on what you want to achieve, you would need the appropriate type of network cable. UTP-CAT5e is the most popular UTP cable; it replaced the old coaxial cable that was unable to keep up with the constantly growing need for faster and more reliable networks.

Here's what IT pros need to understand about the types of network cables, and cabling history and fundamentals, as new technology comes to market.

Geo-fencing (geofencing) is a feature in a software program that uses the global positioning system (GPS) or radio frequency identification (RFID) to define geographical boundaries.

Geo-fencing allow an administrator to set up triggers so when a device enters (or exits) the boundaries defined by the administrator, an alert is issued. Many geo-fencing applications incorporate Google Earth, allowing administrators to define boundaries on top of a satellite view of a specific geographical area. Other applications define boundaries by longitude and latitude or through user-created and Web-based maps.

Geofence virtual barriers can be active or passive. Active geofences require an end user to opt-in to location services and a mobile app to be open. Passive geofences are always on; they rely on Wi-Fi and cellular data instead of GPS or RFID and work in the background.

The technology has many practical uses, including:

What is geofencing? This definition explains how software using global positioning system (GPS) or radio frequency identification (RFID) to create a virtual barrier.
