Benefits of the Solar Kit Deye 8kw with 16 Tongwei panels and Battery V-Tac 14,33KWh

Great capacity with a single connection

The V-TAC VT-14033 meets 14,33kwh nominal in a single team of 280Ah. There is no need to join several modules, or manage parallel cables, or distribute the space between several units: a single battery, a single connection point to the inverter and communication by CAN. It is a direct way of having a lot of storage with the minimum assembly. You can compare other capabilities in our section of lithium batteries.

Discharge power near the inverter

The Deye SUN-8K-SG05LP1-EU can upload and download batteries up 190A. The V-TAC supports 140A continuous and 130A as standard current, that is, around 7,2kw and 6,7kw at nominal tension. In practice, the battery alone can feed almost all the power of the inverter during the night, something that with small modules would require two or three units. In addition, its internal resistance of 16MΩ reduces heat losses to those currents.

10,08kWP exploited without clippings

Thanks to his 26A by MPPT, the inverter admits without limiting the workstream of 15,33A of the Tongwei 630W panel, and its entry 10.400W accept with margin 10.080Wp of the kit. The SUN-8K is the upper model of the SG05LP1 series, one of the ranges of inverters hybrid of Deye with more presence in housing, with 6 programmable time slots, entrance to diesel generator and compliance with RD 140 and UNE 217002.

Long-lasting Bifacial N-Type panels

The 16 tongwei TNC 2.0 modules combine 132 average N-type cells, , double glass of 2.0 mm and iP68 connection box, with a temperature coefficient of -0.28%/°C which reduces losses in summer. Your bifiality of 80 ± 5% sum production thanks to the reflected light, and Tongwei guarantees the 87.40% of the power at 30 years. Consult the entire range of solar panels.

Complete installation in Tienda Solar with our structures for solar panels for tilted cover, flat or floor, and with the wiring and protections needed.

System technical configuration

Distribution of panels: Two series of eight

The 16 modules are divided into equal parts between the two MPPT entries of the inverter, with 8 panels in series in each one. It is the option that best fits the equipment tension window:

• Working voltage (VMP) per series: 328,8V, comfortable within the MPPT range 150-425V.
• Tension in circuit opened by series (STC:) 396V.
• Maximum stress estimated in winter (-10 ° C:) some 429V, calculated with the VOC coefficient -0,24%/°C, with margin with respect to the limit of 500V.
• Workstream: 15,33A per series, well below the 26A of each MPPT.
• Overdimensioning DC / AC: 1,26 (10.080WP for 8,000W nominal), within the maximum FV Entrance of 10,400W.

Compatibility between the V-TAC battery and the inverter Deye

The working range of the battery 43,2V (end of discharge) to 57,6V (load), is inside the battery window of the inverter, of 40-60V, and both teams communicate by CAN. In this kit the current limit marks the battery (140A), below the 190A of the inverter. V-TAC recommends loading to 130A in constant current until 57,6V and end up in constant tension until the current goes down 14A.

Orientation production and autonomy

With 5 hours solar peak of average and a global performance of 80%, the 10,08kwp would generate some 40kwh a day of average annual. Take the 90% depth of discharge of the manufacturer's reference, the battery would offer some 12,9kWh Usage (estimated calculation), almost a third of that production, and some 13 hours supply with a medium night consumption of 1kw. Are reference values; in the Blog Tienda Solar our experts explain how to calculate production and storage for your home.

Where to install the battery

The VT-14033 measures 660 x 154 x 900 mm (background x wide x high) and has iP20 Protection, so it should be installed in interior, in a dry and ventilated space. Burden 0 and 60 ° C and download between -20 and 60 ° C.

Who is this kit for?

Housing with high consumption of day and night

The 10,08kwp cover the daytime, pool or teleworking diurnal consumption, and 14,33kwh battery moves surpluses in the evening and night.

Homes that are going to electrify their consumption

If you plan to install a aerotermia, a induction plate or a electric car charger, this kit offers from the beginning the generation and storage necessary to absorb this increase in consumption.

Installers that prioritize simplicity

A single large-capacity battery and a calculated strings configuration reduce the design and assembly time. For other combinations of power and storage, consult our solar kits or the full range of inverters solar.

Frequently Asked Questions (FAQ)

1. How do the 16 panels connect to inverter Deye of 8kw?

They are distributed in two series of 8 panels, one in each MPPT. Each series works for some 328,8V and, on cold days of -10 ° C, it does not exceed the 429V in open circuit, below the maximum 500V. The current of 15,33A per series is far from the 26A that supports each entry.

2. Can the V-TAC battery deliver the 8kw from inverter?

Almost. The VT-14033 supports 140A continuous, some 7,2kw at nominal tension, in front of the 190A that can handle the inverter. For the normal use of a home is more than enough; The point peaks above that out-of-sun power are covered from the network.

3. How much useful energy does the battery have?

Its nominal capacity is 14,33kwh. The manufacturer defines its useful life to 90% depth of discharge, which is equivalent to some 12,9kwh usage by cycle. Real energy available also depends on the download settings of the inverter.

4. Does the system work during a light cut?

Yes. The inverter can work on isolated with the energy of the panels and the battery, and it admits twices of double their nominal power for 10 seconds to start engines and compressors.

5. Can I legalize the installation to compensate for surpluses?

Yes. The inverter Deye complies with network connection regulations RD 140 and UNE 217002. An authorized installer must take care of legalization and procedures with the distributor and the marketing machine.

6. What guarantees do the components have?

The tongwei panels they have 12 years of product guarantee and 30 years of linear power guarantee, and the inverter Deye with 5 or 10 years according to the final installation site. The V-TAC battery is covered by the manufacturer's warranty; Consult us the current conditions before purchase.

7. How much surface does the 16 panels need?

Each module measures 2.382 x 1.134 mm and weigh 32,2kg, so the set occupies some 43m² without counting separations. If you already have a inverter networking, the Deye supports coupling AC to integrate that installation.
