THE BATTERY BANK

WARNING: Never mix and match batteries in the battery bank. All batteries must be the same type, size, and general age. An old, mismatched, or shorted battery in a bank causes a lot of problems. NOTE: New batteries act like old batteries and will need a few cycles before they operate correctly.

1. WHAT IS THE BATTERY BANK CAPACITY OF 15kW-20/30kWh LFP ESS?

The 15kW-20/30kWh LFP ESS uses 2x or 3x well-known DYNESS Powerbox G2 Lithium-Ferro-Phosphate (LFP batteries with a total capacity of 20,480/30.720Wh in parallel. Patented structure design with high utilisation of active material, maximum improve the utilisation rate of active material and the utilisation ratio of battery internal space. High performance for large current discharge.

2. WHAT IS THE CYCLE LIFE OF THE BATTERY?

Dyness Powerbox G2 batteries are designed for unlimited cycles/10 years @95% DoD (Depth of Discharge).

3. HOW CAN I GET THE LONGEST LIFESPAN FROM THE BATTERY?

1. It is required to charge the battery at least once every 6 months, for this charge maintenance make sure the SOC is charged to higher than 90%
2. Every year after installation. The connection of power connector, grounding point, power cable and screw are suggested to be checked. Make sure there is no loose, no broken, no corrosion at connection point. Check the installation environment such as dust, water, insect etc. make sure it is suitable for IP20 battery system.
3. If the battery is stored for long time, it is required to charge them every six months, and the SOC should be higher than 90%

4. WHAT ARE THE BATTERY CARE AND STORAGE INSTRUCTIONS?

1. If the battery is stored for long time, it is required to charge them every six months, and the SOC should be no less than 90%
2. Battery needs to be recharged within 12 hours, after fully discharged
3. Do not install the product in outdoor environment, or an environment out of the operation temperature or humidity range listed in manual.

5. WHEN TO CHARGE MY PYLONTECH LIFEPO4 BATTERY?

If LiFePO4 batteries are not fully discharged, they do not need to be charged after each use. LiFePO4 batteries do not get damaged when left in a partial state of charge (PSOC). You can charge your LiFePO4 batteries after each use or when they have been discharged up to 95% DOD (5% SOC).

6. WHAT TO DO IF THE LOSS OF POWER OF THE BATTERY BANK IS TOO QUICK?
Check if there are any high-power electrical appliances connected. The Off-grid Energy Storage System's battery capacity is 20kWh or 30kWh. Normally, if the power of a connected electrical appliance is ~2000W and the battery is discharged from 100% to 10%, the battery will run out in about 9 or 13.5 hours, respectively.

DC TO AC INVERTER

1. WHAT DOES A POWER INVERTER DO?

A power inverter is a device which converts battery power into mains power, i.e. it transforms 48V direct current (DC) into 230V alternating current (AC). 230V AC is the power supplied to our houses by utility companies, and this is the power required by most normal household appliances such as lights, TVs, fridges etc. There are two main types of inverters:

• Off-grid inverters, which work as a standalone system and require batteries (typically used in caravans, boats or locations without access to mains power)
• On-grid or grid tie inverters, which require mains power to work (typically used in household solar systems and take input directly from solar panels)

In the 15kW-20/30kWh LFP ESS TBB TYRANN 15W 48V Pure Sine Wave Inverter Charger is used - i.e. the inverter can be used to build a home 230V "grid".  

2. WHAT TYPE OF INVERTER IS USED IN THE 15kW-20/30kWh LFP ESS?

The type of power inverter which is used in the 15kW-20/30kWh LFP ESS is a pure sine wave inverter charger rated 15000W. The pure sine wave inverter provides an output of up to 15000W which follows a sine wave harmonically. This is similar to utility-supplied grid power. This inverter switches polarity ("+" and "-") between power cables smoothly; gradually increasing or reducing the voltage as required (in case you were wondering why inverters have to switch polarity: this is the essence of alternating current; polarity changes occur approximately 50 times per second).

3. WHAT ARE THE KEY FUNCTIONS OF 15000W 48V INVERTER CHARGER?

1. The 15000W 48V Pure sine wave inverter: Converts DC current into 230V AC mains electricity, to run various household appliances such as a TV, laptop, fridge, microwave, lighting etc. Able to generate 15000VA of continuous power with a strong peak power handling capability of up to 45000VA (to start powerful appliances with electric motors such as pumps, a vacuum cleaner, power tools etc). This inverter is a pure sine wave type, which easily surpasses modified sine wave inverters in terms of efficiency and compatibility with a wider range of appliances.

2. Enhanced 200A Smart battery charger: Designed to enable safe, efficient, and fast (up to 200A) unattended charging of a battery from a mains power source or generator, with full overcharge protection and multiple charging stages.

3. System expansion potential: This inverter has the ability to be connected in parallel with additional identical units (maximum of 3 total inverters), offering the possibility of large-scale system expansion, with up to 48kw of power handling capability. Once connected in parallel, there is the option for 3-phase operation (ideal if the system is being used to power industrial grade equipment and machinery run on 3 phase).

4. WHAT ARE THE ADDITIONAL INTELLIGENT FUNCTIONS OF THE TYRANN 15000W 48V HYBRID INVERTER?

The TYRANN 15000W 48V hybrid inverter boasts an abundance of unique features, providing enhanced functionality over standard inverters. These include:

- Customisable settings: Easily adjust parameters such as battery type, AC input range, charging current, high/low voltage disconnect, charging stages, auto-restart, and power-saving modes through an intuitive interface. 

- Compatibility: The TYRANN inverter is compatible with the TBB Solar Mate SP600 600V 120A MPPT solar charge controller (included), allowing users to integrate solar energy into their power system.

- LCD monitoring screen: The optional E4 LCD Monitor displays real-time data including voltage, frequency, battery levels, and load percentages, making it simple to monitor performance and adjust settings.

- Integrated load management system: Manages power distribution across connected devices, optimizing energy use and preventing overloads for reliable, balanced performance.

- Advanced communication and remote monitoring: Users can easily monitor performance through the Nova Web and mobile app via the TBB-KIN2 Kinergy-II Wi-Fi module, this allows for control and adjustments from anywhere.

- Advanced battery management: Compatible with various lithium and lead-acid (GEL/AGM) batteries, featuring overcharge protection, AGS (Automatic Generator Start), and power assist, providing seamless power support across different applications.

5. WHY ARE A 48V BATTERY BANK AND 48V DC TO 230V AC INVERTER IS USED?

This setup will provide some important benefits:

• The input current for the inverter will be four/two times smaller for 48V than for 12V or 24V, making the inverter and the entire system safer and more reliable;
• The cables between your battery and the inverter do not have to be as thick as those used for a 12V or 24V battery bank and inverter.

6. WHAT AC INPUTS/OUTPUTS DOES THE TYRANN 15000W INVERTER HAVE?

1 x 230VAC INPUT / 1 X 230VAC OUTPUT.

7. DOES THE TYRANN 15000W POWER INVERTER HAVE WIRELESS CONTROL?

YES (as an option). Users can easily monitor performance through the Nova Web and mobile app via the TBB-KIN2 Kinergy-II Wi-Fi module, this allows for control and adjustments from anywhere.
