Benefits of the Solar Kit Deye 8kW with 2 batteries of 5,12kwh and 16 Tongwei panels

A bank of batteries at the height of the inverter

With a single 5,12kwh battery, the power that can deliver storage stays in some 5kw. With two modules SE-G5.1 Pro-B in parallel, the maximum current of the bank goes up 200A and the limit becomes that of itself inverter, of 190A. The result is a balanced system: At night, the house can pull the battery with the full power Deye of 8kw, and during the day the surpluses are stored at a much higher rate.

More energy saved for afternoon and night

The 9,2kWh useful they duplicate the capacity of the version with a battery and allow covering the evening consumption peaks: electric kitchen, , washing machine, , air conditioning or lighting. It is a configuration designed to raise the percentage of self-consumption and reduce the energy purchased in the most expensive hours. If you want to compare with other models, visit our section of lithium batteries.

10KWP generation used in full

The SUN-8K-SG05LP1-EU is the upper model of the SG05LP1 single-phase series, one of the families of inverters hybrid of Deye more present in housing. Their 26A by MPPT cover without clippings the imp of 15,33A of the Tongwei 630W panel, and its entry 10.400W admit the 10.080Wp of the kit. In addition, it allows programming 6 slots, upload from a diesel generator and work in parallel with up to 16 teams, and meet RD 140 and UNE 217002.

Tongwei double glass modules

The 16 panels TNC 2.0 integrate 132 average N-type cells, , 2.0 mm glass on both sides and iP68 connection box. With a temperature coefficient of -0.28%/°C and bifiality of 80 ± 5%, they maintain high performance in summer and take advantage of the light reflected on the back side. Tongwei guarantees the 87.40% of the power at 30 years. Discover the entire range in our category of solar panels.

Installation design

Strings: 8 panels in series by MPPT

The 16 modules are connected in two eight strings, one for each MPPT:

• Working voltage by String (VMP:) 328,8V, within the MPPT range 150-425V.
• Tension in circuit open by String (STC:) 396V.
• Open circuit voltage estimated at -10 ° C: some 429V, with the VOC coefficient of -0,24%/°C, below the limit of 500V.
• Current by String: 15,33A, in front of the 26A admitted by MPPT.
• DC / AC RATIO: 1,26 (10.080WP versus 8,000W nominal.)

Connection of the batteries

Both SE-G5.1 PRO-B they join in parallel with the cable 3U-Lbcable150, which transmits power and communication between modules, and the set connects to inverter with the cable 3U-Lpcable1500 for CAN or RS485. They can stack on the floor with the supports included, wall or mounted on a rack of 19 ". Each module weighs 45kg and measures 440 x 133 x 540 mm; being IP20, they must be installed indoors.

Balance between production and storage

With 5 hours solar peak of average and a global performance of 80%, the 10,08kwp would produce some 40kwh a day of average annual, as an indicative reference. The 9,2kWh useful of batteries allow you to keep almost a fourth part of that energy; The rest is consumed directly or poured into the network. With a mean night consumption of 1kw, the battery would cover some 9 hours. To adjust these figures to your case, consult the guides of our experts in the Blog Tienda Solar.

What housing is ideal for?

Large homes with consumption distributed during the day

Housing aerotermia, , swimming pool, , telecommuting or electric vehicle take advantage of the 10kwp during the day and the 9,2kwh battery in the afternoon and night.

Homes that need powerful support

On isolated, the inverter supports twices of double their nominal power for 10 seconds, and the two battery bank can hold high loads during a supply cut.

Installers seeking a balanced system

Inverter, photovoltaic field and storage already sized each other reduce the design time. For other configurations, consult our solar kits or the full range of inverters solar.

Frequently Asked Questions (FAQ)

1. What changes when moving from one to two batteries with the inverter Deye of 8kw?

With a battery, the power available from the storage Round the 5kw (100A). With two, the bank admits 200A and the system is limited by the 190A of the inverter, so you can feed the house 8kw sunless For continuous use, optimal is to work close to the recommended current (2 x 50a), some 5kw, and reserve the maximum power for peaks. In addition, useful energy goes from 4,6kwh to 9,2kwh.

2. Can I add a third battery later?

Yes. The SE-G5.1 PRO-B supports up to 32 units in parallel without external configuration and 64 in Total (327KWh). With a generator of 10kwp, expand to 3 or 4 batteries it allows to store a larger part of daily production.

3. How many Strings do I need for the 16 panels?

Two Strings 8 panels in series, one by MPPT. Each String works for some 328,8V and it does not exceed the 429V in circuit open at -10 ° C. It is not recommended to divide them into 4 strings of 4: the tension of work, some 164V, i would be too close to the MPPT minimum.

4. Does the kit make it compensate for surpluses?

Yes. The inverter complies with spanish regulations RD 140 and UNE 217002. An authorized installer must legalize the installation and process the compensation with the distributor and the marketing machine.

5. What autonomy do I have during a blackout?

The inverter it works in isolated with the energy of panels and batteries. With 9,2kWh useful, autonomy depends on consumption 1kw on average they would be some 9 hours, and less if there are high loads such as air conditioning or kitchen.

6. What guarantee do the components have?

Tongwei panels: 12 years of product and 30 years of linear power. . Batteries Deye SE-G5.1 PRO-B: 10 years. . Inverter Deye: 5 or 10 years according to the final installation site. In all cases, the warranty conditions of each manufacturer apply.

7. What surface and what structure do panels need?

The 16 modules 2.382 x 1.134 mm and 32,2kg each, they occupy some 43m² without counting separations. Support 5,400 Pa of front loading and 2,400 Pa back; choose the structure according to your cover and the wind and snow load of the area.
