UPS-PL2448-40L

We don’t offer rackmounts, other than the built-in 1U included in the STL enclosure, but they are available in the open market.

LIT is a battery settings mode.  When switching to LIT, the S parameters should be the same as the previous default settings.

When battery voltage falls below 10V the battery BMS disconnects the battery discharge. As soon as there is PV voltage the battery BMS connects the charge and discharge. We recommend the customer set the LOAD Output turnoff at 11V so tha load disconnects before the battery BMS disconnects the discharge.

We recommend that you just leave the parameters set to AGM Lead Acid. This is how the Lithium battery BMS is designed. The AGM Lead Acid settings in the charge controller are compatible with the battery BMS.

You won’t see voltage spikes when connected to the battery (BMS), even if the battery BMS disconnects the discharge.  No firmware updates are available or needed to switch from AGM lead acid to lithium.

Before Troubleshooting Make Sure:

• back voltage switch is set for your AC voltage (115VAC or 220VAC)
• Battery type is set to GEL (for GEL or AGM) or WET for automobile type batteries.
• the Battery Switch on the front is switched to ON. This can be switched to OFF to disconnect the battery from the charger.
• LOAD – Load power is on. The load will turn off when battery voltage is too low and will turn back on when battery voltage reaches a stable voltage.

Batteries

When testing batteries that are wired in parallel, you must disconnect the battery, so it is isolated from other batteries. When batteries are wired in series you can test each battery without disconnecting them. A fully charged 12V battery will have a battery voltage greater than 12.5VDC without a load.

To see if you have a bad cell, disconnect any load and fully charge the battery, wait a few minutes, measure and record the battery voltage, wait at least 15-30minutes and measure the battery voltage again. The voltages should be within about 0.5V of each other. If the 30minute measurement is too low, then the battery is not good and should be replaced. Tycon Batteries are designed to be charged with Tycon Chargers that are designed for AGM or GEL batteries. Using automobile chargers can be used in an emergency but they shouldn’t be left connected to the battery for a long time or the battery will be damaged. We recommend not to exceed 4hrs if connected to an automobile battery charger. And only use for emergencies, not for regular charging. Tycon Batteries should never be left in a discharged state, especially in cold weather. If your UPSPro® or RemotePro® system is having charging issues, be sure to make sure that you disconnect the load and leave the batteries in a charged state while troubleshooting. Leaving the batteries in a discharged state for a few days or a week can kill the battery, permanently.

RemotePro® and UPSPro® systems are designed to maintain proper battery charge within a defined range. Our systems have protections for over-discharge of batteries but batteries also self-discharge over time, so if they are left without any charge or maintenance for a long time (normally over 6 months) they will continue to self-discharge. Our systems are not designed to restore a battery function if the battery gets over discharged. Our systems work within the range of 0% (13VDC) to 100% discharge (10VDC) on batteries. If batteries are less than 10VDC the user must recondition the battery by charging the battery with a good quality automotive battery charger (6A to 25A). We find that manual type chargers work best.

1. Troubleshooting Battery Problems: Measure battery voltage of individual batteries. Voltage should be >10V. If less than 10V* the battery must be reconditioned. If there are multiple batteries, measure all batteries and compare the voltages. They should be within 1V of each other. If some batteries are lower. Recondition the low voltage battery or all the batteries to get them back to a balanced starting point.

2. Reconditioning Batteries: Recondition batteries by charging for no more than 24hrs with a good quality automotive battery charger. Let batteries sit for another 24 hours and then measure voltages. A fully charged battery will be around 13V. If voltage drops below 12V after 24hours, the battery cannot hold a charge and needs to be replaced. Note: On the large ground mount AL enclosure, the batteries are 6V batteries, so the minimum voltage is 5V.

To figure out how long a battery backup system will keep your equipment powered there is a fairly simple calculation you can do:

((Battery Capacity (Ah) x Battery Voltage (12V)) x Percent Discharge (50%)) / Your Equipment Load (W)

So let’s say your 12V battery capacity is 100Ah and your equipment load is 50W. We use 50% discharge because you really don’t want to discharge batteries much more than 50% if you want them to have a long life. 100Ah x 12V = 1200Wh – 1200Wh * 0.5 (50% discharge) = 600Wh (adjusted battery capacity) 600Wh / 50W = 12hrs backup time. As you can see, with 100Ah of battery and 50W load, your backup time is at least 12 hours.

Factors that contribute to the time to recharge:

1. Your load that is drawing power from the batteries
2. The battery capacity
3. The amount the batteries are discharged.
4. The amount of input power available to recharge the batteries.

Let’s assume you have a Tycon RPSTL12/24M-200-340 RemotePro solar power system. This system has 200Ah of batteries and 340W of solar. Let’s assume your Load is 1.5A @ 24V. To make calculations easy, you want to convert battery capacity and load to watts:

• Battery Capacity: 200Ah * 12V = 2400 Whrs
• Load Power: 1.5A x 24V = 36W

Scenario#1 Batteries are fully discharged, and we are recharging with solar.

• 2400Whrs battery capacity / (340W Solar – 36W Load) = 2400/304 = 8hrs to fully recharge the batteries.

Scenario#2 Batteries are 50% discharged and we are recharging with solar– This is the most common scenario

• (2400Whrs battery capacity / 2) / (340W Solar – 36W Load) = 1200/304 = 4hrs to fully recharge the batteries.<

Scenario#3 Batteries are 50% discharged and we are charging with an AC powered 600W battery charger.

• (2400Whrs battery capacity / 2) / (600W Battery Charger – 36W Load) = 1200/564 = 2.1hrs to fully recharge the batteries.

These are the autonomy calculations

Autonomy = Battery Ah x Battery Volts = Battery Watt Hrs  * 50% battery discharge max = Battery Watt Hr Capacity / Ave Load in Watts = Autonomy Hrs

Ex:

Battery Ah = 180Ah

Battery Volts = 12V

Ave Load – 50W

180AH x 12V = 2160WHrs * 0.5 = 1080WHrs / 50W = 21.6hrs Autonomy

The battery’s voltage should always be higher than it’s standard voltage (12, 24, 48VDC) in order for it to run equipment.  For example: 12VDC battery at float charge should be 13.5-13.8VDC.  If the battery is fully charge but the voltage fails to reach 10.5V, chances are it has a dead cell or two.

You can add a 4.5” double hinged zinc plated safety hasp to secure the door on the Tycon ENC-ST-23x14x12 enclosure with a padlock.

An example of a suitable double hinged safety hasp can be found on Amazon or your local hardware store:

“https://www.amazon.com/dp/B0000CBIEL“

The safety hasp can be mounted to the enclosure using screws or rivets. Be sure to waterproof the screws or rivets with silicon to prevent water leaks into the enclosure.
