Benefits of Lithium Battery V-TAC 16.07KWH VT-48290

In the segment of the 48v large capacity batteries, most manufacturers offer modules of 5 or 10kwh they force to stack several units to reach a full daily reserve. The V-TAC VT-48290 concentrated 16.07kwh on a single team, which reduces wiring, connection points and communications configuration between modules. For a housing with high night consumption, with aerothermia or with electric vehicle, a single unit covers what would normally require two or three standard modules.

Cells of 314Ah: more energy per unit

The jump to the cells of 314Ah it allows to reach the 16,07kwh with a configuration of 51,2V. Is the same tension of working that the inverters solar low tension hybrids more extended on the market, so the battery is integrated into a new or existing installation without changing the system architecture.

Real depth certified durability

Many technical sheets declare life cycles at depths of download of 80% o lower. V-TAC certifies 7000 cycles or more than 90% of DOD, a depth much closer to the actual use of an installation of self-consumption, and fixes the end of life in the 70% residual capacity. This means that, after those cycles, the battery continues to run with a considerable useful capacity.

As a guidance reference (own calculation, not declared by the manufacturer,), 7000 cycles × 16,07kwh × 90% dod equivalent 101MWh accumulated energy during the useful life of the equipment, allowing us to estimate the real cost per kWh stored against alternatives such as gel batteries or the aGM batteries, whose useful life in cycles is significantly lower.

High current for demanding consumption

With 150A loading and maximum discharge at 25 ° C, the battery can deliver a power of approximately 7,68kw at nominal voltage (own calculation: 51,2V × 150a). In practice, this allows to accompany a hybrid inverter single-phase of 6 or 8kw without the battery limit the available power, and absorb the production peaks of your solar panels in the central hours of the day.

News versus the previous version of V-TAC 16.07KWh

On Tienda Solar we also maintain the previous V-TAC battery of 16.07kwh, so it is convenient to know what this new model provides VT-48290:

• Floor format with wheels: facilitates transportation and positioning in garages, storage rooms or technical rooms, something important in a team of 114kg.
• Less height: with 690 mm high and 630 mm wide, your profile is lower and wide, designed to be placed on the ground or under other equipment.
• Documented scalability: the manufacturer recommends 15 modules, which opens the door to systems of more than 240kwh for small shops, ships or agricultural holdings.
• Greater loading temperature range: admits load between 0 and 60 ° C.

Recommended installation and location

A team for interior

The degree of protection IP20 indicates that the battery is designed for interior spaces, dry and protected from dust and moisture. The usual locations are garages, technical rooms or ventilated storage rooms. It should not be installed to the weather.

Temperature and performance

The battery can download from -20 ° C, but solo admits load from 0 ° C. In cold areas of the peninsula, such as the plateau or mountain areas, it is convenient to choose a location that does not fall below 0 ° C in winter so as not to interrupt the solar load.

Configuration with the inverter

Communication CAN allows the BMS to inform the inverter of the state of charge, tension and current limits in real time. When configuring the inverter, it is necessary to respect the 43,2v range at 57.6V and the recommended load current of 140A. In the Blog Tienda Solar you will find purchase guides, technical advice and configuration tutorials prepared by our team of experts.

Who is this battery for?

• Housing with high night consumption: aerotermia, air conditioning, induction cooker or electric vehicle recharge.
• Isolated network facilities: country houses or farms that need several days of autonomy, combining the battery with solar kits complete.
• Professional installers: a single 16kWh equipment reduces the assembly time and the number of connections against several small modules.
• Small shops and ships: thanks to scalability up 15 modules.

Frequently Asked Questions (FAQ)

1. What is the difference between this battery and the previous version of V-TAC of 16.07kWh?

Both offer 16,07kwh to 51,2V with cells 314Ah, but the new VT-48290 incorporates a soil format with wheels, a reduced height 690 mm, a documented scalability of up 15 modules and a loading temperature range of 0 to 60 ° C. The choice depends above all of the available space and the final size of the system.

2. What inverters are compatible with V-TAC VT-48290?

It is compatible with inverters hybrids and chargers low voltage (48V) who admit a working range of 43,2V to 57.6V and communication CAN. Before installation, we recommend that the CAN protocol of the battery appears in the manufacturer's compatibility list of the inverter.

3. How much useful energy can I take advantage of in each cycle?

Working 90% of DOD, which is the depth to which the manufacturer certifies 7000 cycles, the useful energy round the 14.46kwh by cycle (own calculation: 16.07kwh × 0.9). It is possible to use more capacity at a timely manner, but maintaining that margin helps preserve the useful life.

4. Can I connect several batteries in parallel to expand the capacity?

Yes. The manufacturer recommends a maximum of 15 modules, which allows you to overcome the 240kwh storage. If you need a modular solution to start with less capacity, in our category lithium batteries you will find smaller stackable alternatives.

5. Can it be installed abroad or in a garage without heating?

Abroad, since the degree of protection is IP20. In a closed garage yes, as long as the temperature stays above 0 ° C during the load. Below that temperature the battery can continue downloading up -20 ° C, but it will not accept load.

6. How much does it weigh and how it is transported to its location?

The battery weighs 114kg. The wheels of its base allow you to move it by flat surfaces without the need for lifting equipment, although to save steps or unevenness, at least two people's intervention is recommended.

7. Is it uses for a small installation without large capacity batteries?

If you are looking for simple storage for a balcony or a few panel installation batteries Plug & Play or systems with microinverters they can be better adjusted. The VT-48290 is designed for facilities with hybrid inverter of 48V and consumption media or high.
