6kW 7740W Single Phase Off-Grid Photovoltaic Kit with 20kW Growatt Wanroy RACK Battery Storage

6kW 7740W Single-Phase Off-Grid with 20kW Growatt Wanroy RACK storage system for cabins and isolated houses

This photovoltaic system with storage is a system that generates electricity using solar panels and stores it in batteries, without being connected to the public electricity grid. This type of system is ideal for isolated houses, shelters, boats, camper vans or for those who want to achieve total energy independence.
Here are the main components and how an Off-Grid photovoltaic system works:
Photovoltaic panels - capture solar energy and transform it into direct current (DC). The amount of energy produced depends on the number and type of panels installed, as well as exposure to the sun.
Storage batteries - accumulate the energy generated by the photovoltaic panels during the day to make it available at night or when solar energy is not sufficient. The most commonly used batteries are lithium or lead-acid.
Inverter - converts the direct current (DC), generated by the solar panels and stored in the batteries, into alternating current (AC), which is the one used by most household appliances.
Hybrid inverter: Some off-grid systems include an inverter that also allows you to connect a generator or other power source as a backup, for emergency situations.

2 integrated MPP trackers
The spf6000 has two integrated MPP trackers. These trackers ensure that the optimum power point of the solar modules is found and that the maximum available power is obtained from the modules. By using two MPP trackers, the inverter can work more efficiently, especially if the Solaranlage consists of modules with different characteristics or is at different tilt angles. This allows the individual MPPTs to work independently of each other and achieve the optimum output from the solar modules, resulting in improved overall efficiency of the Solarasystem. The maximum input current per MPP tracker is 16A.
Configurable grid or solar input priority
The configurable grid or solar input priority in the Growatt spf 6000 es Plus enables individual energy optimization. You decide whether solar energy or the power grid is used as a priority. This adjustment ensures a reliable energy supply - perfect in areas with an unstable power supply or for renewable energy priorities. This function increases independence from the power grid and ensures flexible energy management according to your preferences, while ensuring a constant supply.
Equalization charging function
The equalization charging function in the spf 6000 es Plus optimizes battery life by keeping the cells evenly charged. This prevents overcharging and discharging, making the battery usable for longer. This minimizes capacity loss and ensures sustained stable performance over time. Intelligent and automatic, this function ensures that your battery bank is always in top condition, increasing the overall performance of the system and making your off-grid energy solution reliable.
Time-controlled charging and power control
The Growatt spf 6000 es Plus inverter offers time-controlled charging and precise power control, making your energy management even more efficient. With the time-controlled charging function, you can specify the times at which the inverter charges the batteries preferentially. This allows you to make optimum use of the solar energy during the hours with the highest solar radiation and thus increase the battery capacity for later consumption. The power control of the spf 6000 es Plus allows you to precisely monitor and adjust energy production and use. You can fine-tune the output power of the inverter as required and thus ensure that your energy supply meets the current requirements. This function is particularly useful for managing unexpected power peaks or controlling the start-up of energy-intensive devices, while ensuring the stability and reliability of your power supply system.
