GTIS Power and Communications Systems
Description
This system is the UPS described in Karl’s Blog post here. It does not include any batteries nor the mounting board. Nor does it include a Surge-protector/power strip needed to protect the chargers. It does include the 2 chargers, Phoenix inverter, a completed wiring harness and fuseholder with two 150A fuses.
What this product does: Use this when you need a UPS that can run for more than half an hour or if you want better protection from surges coming down the power lines. Combine with one or more large 12-V, deep cycle batteries, sold separately, to make a long-running uninterruptible power supply (UPS) for powering computers or network equipment during power outages. Your loads are always powered by the pure sine wave inverter for excellent isolation from AC line surges noise and voltage fluctuations. AC line power is used to charge the batteries when it is available.
Recommended use(s): Perfect for powering your NAS server and network switches through long power cuts. This UPS system can power several desktop computer systems or up to ten laptop computers. This system can power up to 640W of continuous loads. Note that the higher your loads, the longer it will take to recharge the batteries after a power outage.
Batteries not included: This system can be programmed to use LFP or lead-acid batteries, assuming you can find some locally. Contact us if you’d like us to purchase and ship batteries to you. 100Ah is the smallest 12V battery this system should use. LFP batteries are much preferred for this system because of their heat tolerance, longevity, and lower lifetime cost. But “deep cycle” AGM or Gel batteries will also work well. Up to 3 batteries in parallel can be used to get even longer run times, but if using LFP batteries, check the user’s manual to verify if they are allowed to be connected in parallel. It varies depending on the manufacturer.
Estimating Runtime: The inverter should be programmed to cutoff when a Lead-acid battery is depleted about 50%, so available energy is 50% of the Amp-hour rating of your battery multiplied by 12v. For a 100Ah battery that comes to 600 watt-hours. Divide 600 by the average power draw of your equipment ( in watts) to estimate the hours of run time. For lithium batteries, use 90% of their rated capacity for your run-time estimate.
A single 100Ah LFP battery or a 200Ah AGM battery will give you almost 2 hours of run time if the system is loaded at the maximum of 640W. With more modest 300W of loads, run time is about 4 hours.
Advantages of this product: Extra lightning and surge protection! This UPS is always running from 12V DC, so none of the dirty AC power from your power company gets passed through.
Manufacturer’s info: Phoenix inverter, Blue Smart IP22 chargers
Availability: As of March 2024 – One in Stock! After that one sells, this will be a Custom Build; expect 4-6 weeks before we can ship to you.
