Lithium Battery BK215 Plus 2,15KWh Sunenergyxt Compatible Microinverters

Benefits of the SunenergyXT BK215 Plus

The Sunenergyxt bk215 plus solve one of the main challenges of the Balcony Solar Kits: What to do with the solar energy that is generated during the day but it is not consumed at that time. Thanks to his 2.150Wh LifePo4 battery, this system automatically stores the photovoltaic surplus and makes available to the home in the afternoon, during the night or on days of low solar radiation, reducing the consumption of the electricity network and significantly increasing the self-consumption rate, without the need for a complex installation.

Unlike a system with inverter integrated, this module is designed to work together with microinverters external like Apsystems or Deye, what gives great flexibility: the user can choose the microinverter that best suits its configuration of solar panels and connect it directly to the outputs of the BK215 PLUS. For each photovoltaic entrance you can connect two solar modules, in series or in parallel, according to the tension of the used.

Another of the great benefits of this system is your modular and scalable architecture: starting from a single base module of 2,15kWh, it is possible to add up 7 units of expansion B215 Plus, reaching a total capacity of 17,2kwh, without the need to replace the main team or change the technological platform. The modules can be stated vertically or standing next to each other, adapting to the space available on balcony, terrace or carport.

In terms of durability, their cells Lifepo4 they offer more 6,000 load cycles, and the system incorporates multiple protections of hardware and software (overvoltage, overcurrent, deep discharge, overload, temperature and short circuit) that guarantee safe operation for years, backed by its certification Ip65 that allows the installation abroad without additional protection.

Extension with EV3600 and compatibility with Microinverters

One of the aspects that differentiate the BK215 Plus from other storage systems for balcony is its compatibility with the optional module Sunenergyxt ev3600, which allows the battery to be loaded further from a conventional 230V plug. This opens the door to advanced uses such as the storage of AC of the photovoltaic surplus, the use of dynamic electric rates loading the battery in the cheapest hour, the supply of local emergency energy, or integration with systems of Wallbox and energy management of the home.

In terms of microinverters compatible, the BK215 Plus works with the most common market models, such as those of Apsystems and Deye, which facilitates its integration in existing facilities or on projects where the user has already chosen his microinverter of trust.

If you have doubts about what microinverter combine with this battery, how many expansion modules you need according to your consumption, or if the EV3600 module is suitable for your case, in Tienda Solar we can advise you to configure the complete system. Also, in the blog Tienda Solar you will find purchase guides about Balcony Solar Kits, comparatives between different modular storage systems and technical items on network injection regulations that will help you solve all your doubts before buying.

Frequently Asked Questions (FAQ)

1. Do I need to buy a inverter apart to use this battery? Yes, unlike a battery with inverter integrated, the BK215 Plus is designed to work with a microinverter external, compatible with habitual brands like Apsystems or Deye, that you must acquire separately if you do not have it anymore.

2. How much power can I get with a single BK215 Plus module? With a single storage unit, the nominal output power is 2.000w; When adding a second unit (B215 Plus expansion module), the power increases up 2.400w, staying at that value even if you continue adding more modules.

3. How much can I expand the storage capacity of this system? The base module of 2,15kwh admits 7 units of expansion B215 Plus, reaching a total capacity of 17,2kwh, ideal if your energy consumption grows over time or decides to expand your installation of solar panels.

4. What is the optional EV3600 module for? The Ev3600 allows you to load the battery from a conventional 230V plug, in addition to the usual solar load, enabling uses such as the use of dynamic electricity rates, local energy backup against supply cuts, or integration with wallbox systems and Home Energy Management.

5. Can I install this battery on the outside, on a balcony or carport? Yes, thanks to your certification Ip65, the BK215 Plus is protected against dust and water splash, so it can be installed without problems on balconies, terraces or carports exposed to the weather.
