Pytes V12 (heating, IP66)

Pytes V12 is a large battery for the house, which gathers the current produced by the panels when the sun is out and gives it back in the evening, at night or when the grid is interrupted. The enclosure is sealed and treated against corrosion, so the battery can sit outside, on a wall or on a platform, without needing a technical room. Inside it has a heating pad, a kind of electric blanket for the cells, which allows it to charge in winter as well, when it is below zero outside.

The 11.776 kWh cover, as a guide, the evening and night consumption of an ordinary home, and 90% of this energy can actually be used, the rest remaining as a protection reserve. The battery delivers 100 A continuously, that is 5.12 kW, enough for several household loads switched on at the same time, and 200 A at peak, maintained for over 180 seconds, for starting motors. It occupies 640 x 230 x 520 mm and weighs 100 kg, so it needs a solid wall or a firm base and two people for installation. The heating pad raises the temperature by 8 degrees C per hour, and the 6000 declared cycles mean, as a guide, more than 15 years at one charge-discharge per day. The warranty is 10 years, with at least 70% of the capacity retained at the end.

Voltage range 47.5-57.6 V at 51.2 V nominal, 230 Ah, recommended current 100 A when charging and discharging, peak 200 A maintained for over 180 s, DoD 90%, 6000 cycles. Thermal range: 0...55 degrees C when charging, -20...55 degrees C when discharging, with an integrated heating pad of +8 degrees C/h. The equipment includes a DC switch, a pre-charge circuit and, optionally, a fire suppression system; the enclosure is IP66 with class C4-M anti-corrosion treatment. Communication RS485, CAN, WiFi and dry contact; certifications UL9540, UL9540A, UL1973, CEC, SGIP, IEC62619, CE, UN38.3.

Who it suits

Suitable for a house without indoor technical space, which needs a battery mounted outdoors and which must charge in the months with negative temperatures as well.

Terms explained

• IP66: The code that shows how well the enclosure is sealed: the first 6 means dust-tight, the second 6 means resistant to powerful water jets, so the battery can stay outside in the rain.
• Depth of discharge (DoD): The part of the battery's energy that you can actually use; 90% means that one tenth always remains unused, as a reserve for the health of the cells.
• Dry contact: A simple electrical contact, without its own voltage, through which the battery can start or stop another piece of equipment, for example a generator.

Technical specifications

Recommended applications

• Residential storage with outdoor installation

Technical details

Specifications confirmed from the manufacturer's datasheet

Pytes V12 is a monobloc LFP battery of 11.776 kWh, with 230 Ah at 51.2 V and a working range of 47.5-57.6 V. The recommended charging/discharging current is 100 A (5.12 kW), with a peak of 200 A maintained for over 180 seconds. The depth of discharge is 90%, and the declared service life is 6000 cycles.

The IP66 enclosure with class C4-M anti-corrosion treatment allows outdoor installation, on a wall or on the ground, the dimensions being 640 x 230 x 520 mm at a weight of 100 kg. The integrated heating pad raises the temperature by 8 degrees C per hour and allows charging at negative temperatures; the working range is 0...55 degrees C when charging and -20...55 degrees C when discharging. The battery includes a DC switch, a pre-charge circuit and, optionally, a fire suppression system. Communication is through RS485, CAN, WiFi and dry contact. Certifications: UL9540, UL9540A, UL1973, CEC, SGIP, IEC62619, CE, UN38.3.
