Benefits of Lithium Battery V-TAC 16.07KWH IP65 VT-48290

Most of the low capacity low voltage batteries of the market are manufactured with envelopes IP20, designed exclusively for dry and clean interiors. The V-TAC VT-48290 IP65 break that limitation: it maintains one of the highest capabilities per unit of the residential segment, 16.07 kWh in a single module, and combine it with a sealed enclosure it allows to install it where there is really space, like a garage with dust, an outdoor area or a room of facilities with environmental moisture.

In front of solutions that force three or four small modules to reach the same energy, here everything is concentrated in a single unit of 314 ah, which reduces wiring, connection points and installation time. If you are comparing alternatives, in our category of lithium batteries you will find other capabilities and formats to size each project.

In performance, the maximum current of 150 A allows you to deliver from the order of 7,68 kW, a figure that covers the simultaneous start of high consumption appliances as the induction plate, the oven or a heat pump. The cAN with the BMS facilitates integration with most inverters hybrid low voltage, which manage the loading and unloading depending on the actual state of the battery.

Durability is another strong point: the manufacturer certifies 7,000 cycles or more than 90% depth of discharge, and the technical sheet indicates also 7,000 cycles or more until reaching 70% capacity (eol). All this supported by a 10-year warranty, one of the reference deadlines in residential storage.

IP65 protection: what it means in a solar battery

The code IP (Protection Inputs) it is composed of two figures. The first, 6, indicates maximum protection against solids: the equipment is totally sealed to dust, something key in garages, agricultural ships or rural areas. The second, 5, certify the water jet resistance thrown from any direction, so splashing, rain-dragged rain or hose cleaning do not compromise internal electronics.

This does not mean that it must be exposed directly to the sun or the weather without any shelter. To lengthen the life of the cells, it is advisable to locate it under cover, in the shade and with ventilation, respecting the temperature ranges indicated by the manufacturer.

Real useful energy and estimated autonomy

Working 90% depth of discharge, the battery makes available some 14.46 kWh useful by cycle. By way of manner, with a constant average consumption of 1 kw (refrigerator, lighting, router, standby and a punctual appliance), that energy would give for something more than 14 hours of autonomy, enough to cover the full night of a house with moderate consumption and reach the next morning, when the solar panels return again.

IP65 version or interior version? How to choose your V-TAC 16.07KWh

On Tienda Solar we have two variants of this battery with the same electrical base: 16.07 kWh, 314 AH and 51.2 V. The difference is in the installation environment:

• V-TAC VT-48290 IP65 (SKU 12789:) surround sealed against dust and water, designed to garages, porches, storage rooms, ships and outdoor. It is the right choice when there is no internal internal technician room or space is humid or dusty. According to the image of the manufacturer, it is supplied on a wheel base that facilitates its displacement to the installation point.
• Interior version of the V-TAC battery 16.07kwh VT-48290: without protection IP65, indicated for technical rooms, boiler rooms or dry and clean interiors.

If the battery is going to coexist with moisture, dust or splash, the IP65 version eliminates the risk and avoids having to build a cabinet or additional protection enclosure.

Installation and compatibility of the system

The VT-48290 IP65 is a low voltage battery (51.2 v), so it must be combined with inverters solar hybrid or isolated that work 48 V and admit cAN. Before start-up, it is advisable to verify that the V-TAC battery protocol is figured in the list of compatibility list inverter chosen.

For those who start from scratch, the easiest way to hit is to opt for one of our solar kits, who already group panels, inverter and compatible storage, and complete the installation with structures for solar panels suitable for your deck.

On Tienda Solar we advise professional and private installers in the sizing of each system. And if you want to deepen on topics such as the depth of discharge, the choice of inverter o the maintenance of batteries, in the Blog Tienda Solar you will find purchase guides, technical advice and specialized content prepared by our experts.

Frequently Asked Questions (FAQ)

1. Can I install the V-TAC VT-48290 IP65 battery on the outside?

Yes. Your degree of protection IP65 it dust watertight and water jet resistant, so it is suitable for exteriors and non-conditioned spaces. Even so, it is recommended to locate it low cover and protected from direct solar radiation to keep it within its working temperature range and prolong the life of the cells.

2. Does it work with temperatures below zero?

May download between -20 ºC and 60 ºC, but the manufacturer sets a range of load 0 ºC to 55 ºC. The technical sheet does not specify autoCheating system, so in areas with frequent frost it is preferable to install it in a garage or enclosure that does not lower 0 ° C, so you can load normally throughout the year.

3. What is the difference with the interior version of the VT-48290?

Both share 16.07 kWh, 314 AH and 51.2 V. The version IP65 (SKU 12789) add a sealed envelope that allows you to install it outdoors covered, garages or spaces with moisture and dust, while the interior it is designed for dry technical rooms.

4. With what inverters is it compatible?

With inverters hybrid and inverters insulated low voltage (48 V) have cAN and support the V-TAC protocol. We recommend always reviewing the list of compatibility listing inverter or consult with our technical team before purchase.

5. How much useful energy does it offer and how old can it last?

To 90% DOD provides some 14.46 kWh useful by cycle. With 7,000 cycles or more certificates at 25 ºC, at the rate of a full daily cycle would be equivalent to some 19 years of theoretical use, well above the 10-year warranty from the manufacturer Real life will depend on the working temperature and the use profile.

6. What power can you deliver in consumer peaks?

Admits a maximum loading and unloading of 150 A, what 51.2 V suppose some 7,68 kW. The recommended current for continuous use is 140 A (approx. 7,17 kW). The final power available at home will also depend on the capacity of the inverter installed.
