Lithium Battery V-TAC 48V 200Ah 9,6KWH VT-91600

Benefits of Lithium Battery V-TAC VT-91600

The VT-91600 is positioned as a solid alternative against other market storage solutions thanks to its balance between Capacity, durability and security. Your Certified useful life of more than 6000 cycles At 90% depth of discharge (DOD), maintaining 70% of its capacity at the end of its useful life (EOL), places this battery well above the average of traditional lead-acid batteries, significantly reducing the cost per kWh Stored throughout your operational life.

Your Ultra low internal resistance of 16 MΩ Minimizes heat losses during loading and unloading cycles, improving the overall system efficiency, while its discharge temperature range of -20 ° C at 60 ° C It makes it a specially versatile option for installations exposed to demanding weather conditions. When it is a 48 V system with CAN, the VT-91600 is integrated natively with most inverters hybrid of the market, allowing real-time monitoring of the state of charge, temperature and accumulated cycles. This compatibility also makes it the ideal complement for those who already have solar panels and seek to maximize their self-consumption by storing daily production surpluses.

Compatibility and integration with your solar system

Thanks to its continuous maximum current of 100 a Both on load and unloading, VT-91600 can work in facilities with high power demands without compromising safety or the useful life of cells. Is a battery especially indicated for those seeking to ride a Solar Kit Complete self-consumption, since its 48 V nominal voltage is the standard used by most residential systems and small current commercial facilities. For those looking for more compact storage solutions or simplified installation, in Tienda Solar you will also find alternatives like Batteries Plug & Play, designed for a rapid startup without renouncing the performance of a modern lithium battery.

Recommended loading method

To ensure maximum performance and maximum battery life, the manufacturer recommends a loading process in two stages:

1. Constant current stage (CC): load 90 a constant current until reaching the 54 V.
2. Constant voltage stage (CV): the load is maintained 54 V constants until the load current descends 15.7 a, at which time the load is considered complete.

Following this cargo protocol is essential to preserve the health of lithium cells and ensure that battery reach or exceeds 6000 cycles of life specified by the manufacturer.
