Benefits of the Solar Kit Deye 12kW with battery V-TAC 14,33KWh and 24 panels Tongwei

Large capacity storage without multiplic equipment

To approach the 14,33kwh of the V-TAC VT-14033 with 5KWh modules, three batteries would be needed, with their parallel cables and their space. Here everything fits in a single team of 280Ah, with a single connection to inverter and communication by CAN. Fewer connection points means a faster assembly and fewer elements than to review in maintenance. See other storage options in our section lithium batteries.

More nocturnal power from a single battery

With 140A continuous and 130A standard current, the V-TAC can deliver around 7,2kw at nominal tension, more than double a 5KWh module working on its recommended current. In a inverter of 12kw, that allows you to keep a good part of the usual load of a large home or a small business. Your internal resistance of 16MΩ it limits losses when it works at high currents.

Technical System Details

FV field: Three Strings of eight modules

Each of the 3 MPPT receive 8 panels in series. At the point of maximum power, each string works 328,8V, within the MPPT range 150-425V. In open circuit, the tension is 396V in STC and some 429V at -10 ° C, calculated with the VOC coefficient -0,24%/°C, with margin in front of the 500V maximum. The work stream, 15,33A, he is loose in front of the 26A per entrance, and the 15.120Wp from the field enter the maximum FV power of 18,000W, with a DC / AC ratio of 1,26.

V-TAC battery with inverter Deye

The battery voltage window 43,2V to 57,6V, fits in the battery range of inverter, of 40-60V, and communication is done by CAN. The current limit is fixed by the battery, with 140A, in front of the 250A admit inverter. V-TAC recommends a load to 130A in constant current until 57,6V, followed by constant tension until the current descends 14A.

Production and Reference Autonomy

With 5 hours solar peak of average and a global performance of 80%, the field of 15,12kwp would produce some 60kwh a day. To 90% depth of discharge reference, the battery would offer some 12,9kWh Usage (estimate from its nominal capacity), near a fifth of that production, and some 13 hours supply with a medium night consumption of 1kw. These figures are guidance; in the Blog Tienda Solar you will find guides from our experts to adjust the dimensioning to your real consumption.

Battery location

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. Admits load between 0 and 60 ° C and download between -20 and 60 ° C.

Who is it going?

Business with continued consumption

Offices, businesses or workshops that maintain lit teams at the end of the day (cold chambers, servers, alarms or lighting) take advantage of the 14,33kwh battery after a day of production 15kwp.

Large homes with high demand in the afternoon

Houses with aerotermia, , induction and air conditioning that concentrate a good part of the consumption by falling the sun find a capacity and a discharge power in this battery very higher than those of a small module.

Installers who want to simplify assembly

A single large capacity battery and a validated Strings configuration reduce installation hours. For other combinations, consult all of our solar kits or the range of inverters solar.

Frequently Asked Questions (FAQ)

1. What power can V-TAC battery deliver with the inverter of 12kw?

Until 140A continuous, some 7,2kw at nominal tension. The inverter supports 250A, so in this kit the limit marks the battery. Consumptions that exceed that sun-out power are covered from the network, thanks to 60a network step of the inverter.

2. How much energy can I use the battery?

Nominal capacity is 14,33kwh. Take the 90% depth of discharge with which V-TAC defines its useful life, they get some 12,9kwh usage by cycle. The final figure depends on the discharge configuration of the inverter.

3. How are the 24 panels between MPPT?

On 3 8 panel strings, one by MPPT. Each String works for some 328,8V and it does not exceed the 429V in circuit open at -10 ° C. As the MPPTs are independent, each String can be installed in a different orientation.

4. Does it maintain the supply during a blackout?

Yes. The inverter can operate in isolated with the energy of the panels and the battery, and it admits twices of double their nominal power for 10 seconds. Autonomy will depend on the connected charge and battery status.

5. Is it legalizable to compensate surpluses?

The inverter includes the spanish standard UNE 217002 among its network connection certifications. Legalization and surplus compensation should be processed with an authorized installer, which will also check that supply single-phase admits a team of 12kw.

6. What guarantee do the components have?

The tongwei panels offer 12 years of product guarantee and 30 years of linear power guarantee, and the inverter Deye, , 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 buying.

7. How much surface do panels need?

The 24 modules 2.382 x 1.134 mm and 32,2kg each, they occupy some 65m² without counting separations. If you have a previous installation with a inverter networking, the Deye supports coupling AC to integrate it.
