MODULAR ENERGY STORAGE: RESIDENTIAL AND SMALL COMMERCIAL BATTERY FROM 5.3 TO 79.5Kw

ELECTRICAL SELF-CONSUMPTION WITH BATTERY

Self-consumption with batteries is an interesting alternative, especially for solar energy but also if you are connected to the grid and without photovoltaics.

It presents the opportunity to generate electricity at the right time and use it when needed. Therefore, it allows you double autonomy: you can produce and consume on your own.

In fact, as the current electricity market is regulated, batteries can provide stability to the daytime tariff price. This can be very useful in the residential sector with photovoltaic installations and which send the surplus to the grid. It can also be very interesting in small and medium-sized companies that have tariff contracts (P1-P6).

In the residential sector, if a battery bank is available, a hybrid grid inverter can be used to program battery charging during ‘off-peak’ hours of low tariff prices and to reschedule discharge during peak hours, where the purchase cost is very high. Naturally, if there is a photovoltaic installation, it is possible to avoid sending the surplus produced and allocate it to battery charging. This is feasible with hybrid inverters capable of managing the battery, the photovoltaic input, the public grid and consumption.

In small industries with a fixed contract for time slots (P1-P6), the battery can be a key element in order to maintain the purchase price of peak rates (P1-P3), at a much lower price. In fact, if during the low price or valley rate hours (P5-P6) they are used to charge the battery (with a hybrid inverter) and the battery power is consumed during the peak rate hours (P1-P-3), the savings in electricity costs can be very important.

The savings will come from the energy not consumed from the grid (especially if there is photovoltaic), from having a cost without peak increases (or in any case with much smoother peaks), and with amortization of the fixed battery cost.

The High Voltage series is a high voltage lithium-ion battery system. It provides reliable backup power for supermarkets, banks, schools, farms and small factories to smooth the load curve and achieve maximum load transfer. It can also improve the stability of renewable systems and promote the application of renewable energy.

EMMAGATZEMATGE MODULAR D’ENERGIA: PRODUCTE RESIDENCIAL I PETIT COMERÇ DE 5,3 A 79,5Kw

The modular energy storage system is designed with a high degree of integration, exceptional reliability and long service life. With a wide range of operating temperatures, this system offers extraordinary flexibility and scalability. Each battery module has a capacity of 5.37 kWh. The complete system supports 15 battery modules in series, so its total energy capacity can reach an impressive 79.5 kWh, perfect for any RESIDENTIAL or large-scale INDUSTRIAL AND COMMERCIAL installation up to 768 kW.

WeCo 5K3 XP is the new model from WeCo. It has improvements over the previous model 5K3 HV/LV, such as the introduction of integrated WiFi and Bluetooth as standard. With the new WeCo 5K3 XP we can achieve up to 15 parallels without additional accessories. The WeCo 5K3 XP includes a new generation BMS with dynamic equalizer. WeCo 5K3 XP It is the only lithium battery model on the market patented to operate in high and low voltage thanks to a double BMS.

10.6 A 768 KW The WeCo 5K3 XP lithium battery has a 10-year warranty. The main advantages:

• Universal compatibility: Weco lithium battery has the highest compatibility on the market and can work with communication with the main brands on the market such as Deye, Studer, Schneider, Solax, Victron, Sofar Solar, Voltronic, SMA, Growatt, Goodwee, Imeon.
• Dual BMS for low and high voltage: the 5K3 XP battery has a dual BMS and a dual connection port. If we want to use it in low voltage at 48V we will use the CAN A output and the low voltage connection port. If, on the other hand, we want to use it in High Voltage, we will use the CAN B output and the High Voltage quick connector port. For high voltage it is necessary to purchase the WeCo HV Box accessory.
• Allows 100% discharge: The WeCo lithium battery has 7,800 cycles at 100% discharge. We can completely discharge the battery and use its full capacity. In addition, if we make shallower discharges, such as 80%, we will increase the number of cycles to more than 10,000.
• 1C charging and discharging current: WeCo lithium battery allows charging and discharging at 1C, so with a single WeCo 5K3 lithium battery we can charge and discharge at more than 5,500 Wh (110 Ah) nominal. In just 1 hour we can charge 90% and use 5kW inverters with a single battery without having warranty problems. We can also discharge a peak of 2C (10,000 W) for 30 seconds to initiate high power consumption.
• Operation in extreme temperatures: The WeCo 5K3 lithium battery can be discharged in an extreme temperature range between −20 ºC and +65 ºC and charged between −7 ºC and 55 ºC. No other lithium battery on the market has this temperature range. These are the only lithium batteries certified by telecommunications operators for desert environments. A mountain shelter is also no problem with weco batteries, because their autonomy is even higher than that of lead batteries.

OUR UPS SELF-CONSUMPTION SYSTEM WORKS ON DEYE INVERTERS

Large LCD touch screen for monitoring and configuration. The Deye hybrid inverter has a large touch screen where you can configure all the operating possibilities of the inverter as well as control in the greatest detail the daily production, the battery status, the energy flows and even access the BMS of the lithium batteries to see the cell, temperatures and voltages.

No computers are needed like in other systems, simply from its screen and touch screen we can use and control all the functions of this inverter.

Deye is the most complete hybrid inverter on the market, capable of operating in isolated installations without a grid, with the possibility of being paralleled in single-phase or three-phase in up to 16 devices. Below we will detail its main characteristics:

• 10-year warranty on your Deye hybrid inverters.
• WiFi monitoring included in the Deye hybrid inverter.
• Time programming and deduction of surpluses.
• Compatible with lead, gel and lithium batteries: This equipment allows the use of any type of battery on the market: lead, gel, AGM and is compatible with most lithium batteries.
• Equalization charging available up to 30 W and BMS port for connection to 24 V WeCo or Pylontech batteries.
• Parallelizable up to 16 units.
• Self-consumption operation. Management of surpluses thanks to the Smart Load function and AC coupling of a grid inverter. “Peak Shaving” function to supplement grid power. Deye Hybrid inverters have a function in which they can supplement grid power or a generator with batteries in the case of low-power grids or contracts. If we have 2 kW of subscribed power, for example, we can select the value 2000 W in Peak Shaving and when the demand exceeds 2000 W, the inverter will take the remaining batteries or solar panels to supplement so that the grid does not exceed its subscribed power. This feature is very useful in end-of-line or old transformers where the company cannot supply more energy to the house.
