2 X  48V 50Ah Lithium Battery (5.12 Kwh capacity)

Inverter Description:

This is a multifunctional off grid solar inverter, integrated with a MPPT solar charge controller, a high frequency pure sine wave inverter and a UPS function module in one machine, which is perfect for off grid backup power and self-consumption applications. This inverter can work with or without batteries. The whole system also need other devices to achieve complete running such as PV modules, generator, or utility grid. Please consult with your system integrator for other possible system architectures depending on your requirements. The WiFi / GPRS module is a plug-and-play monitoring device to be installed on the inverter. With this device, users can monitor the status of the PV system from the mobile phone or from the website anytime anywhere.

Lithium Battery Product Description

TL4850ES is the standard 19-inch rack-mounted lithium battery module. It is designed for home and commercial solar energy storage as well as power back up for the critical equipment during the grid power blackout.

TL4850ES uses Lithium Iron Phosphate (LFP) chemistry which is recognized as one of the safest Lithium chemistries currently in use.

The simplicity in modulating the battery makes it possible to create small or large energy storage systems. By adding additional battery modules, the initial energy storage installation can be expanded to a battery group of 8 modules in a single 19-inch rack.

Product Feature

The expected design life is up to 15+ years;

10 years warranty;

Greater depth of discharge (DOD 90%) compared to Lead-Acid/AGM/GEL  battery(DOD 50%);

Single battery module capacity of 2.56kWh;

Working temperatures of between -20°C to 55°C (Charging 0~50°C; discharging -20~55°C);

More stable and safer LFP internal battery cells, allowing an increase in the combustion temperature of 600°C compared to 300°C relative to NMC and LCO;

Battery management system (BMS) automatically manages charge/discharge state and balance current/voltage of each cell. BMS enables protection functions including over-discharge, over-charge,over-current protection and high/low temperature protection;

19 inch standard module battery design, easy installation, DIY friendly and expansion up to 8 modules  that makes the total capacity to 20.48kwh in a single 19-inch rack;

Natural cooling allows the battery to achieve the highest energy efficiency and no fan noise.
