Pytes V15

The Pytes V15 is a battery that keeps the energy produced by the panels and gives it back when you need it. Its role is twofold: it reduces the bill, because you use in the evening the current produced at midday, and it keeps the house supplied when the grid goes down. It is built on Tier 1 type cells, that is from the top quality category, also used in the automotive industry, and it has its own electronic monitoring system that permanently tracks the state of the cells.

The 14.34 kWh covers, as a rough guide, a whole evening and night for a home with above-average consumption. It can deliver 140 A, that is 7.17 kW, continuously — enough to supply several large loads at the same time — and it rises to 300 A, that is 15.36 kW, for 15 seconds, enough to start a pump or air conditioning motor. Of the stored energy you can use 90%, and the declared service life is 6000 cycles, which means roughly over 15 years at one cycle per day. The unit weighs around 135 kg, so it takes two people to handle and it is placed on a solid base. If you later need more autonomy, up to 6 units can be connected in parallel, without replacing the existing battery.

51.2 V nominal, 280 Ah, recommended current 140 A on charging and discharging (7.17 kW), discharge peak 300 A / 15.36 kW for 15 s, DoD 90%, 6000 cycles. BMS with pre-charge circuit and multiple protections, on Tier 1 cells for automotive applications; weight approx. 135 kg, compact format for handling during installation. RS485, CAN, WiFi and dry contact communication, with declared compatibility for over 20 inverter brands, remote monitoring and firmware update. Expansion by connecting a maximum of 6 units in parallel; 10-year warranty.

Who it suits

Suitable for a villa or a home with high consumption, with several powerful loads running simultaneously, that wants the possibility of enlarging the battery bank later.

Terms explained

• BMS: The electronic system that monitors the battery: it measures the voltage and temperature of the cells and stops charging or discharging before anything goes wrong.
• Discharge peak: The high power the battery can deliver for only a few seconds, needed when starting motors; here 15.36 kW for 15 seconds, against 7.17 kW in continuous operation.
• Parallel connection: Connecting several identical batteries so that they work as one, larger one; here up to 6 units, so you can start with one and add more as you go.

Technical specifications

Recommended applications

• Storage for villas and homes with high consumption
• Backup for guesthouses and small commercial spaces
