01 / THE SOLAR ENERGY CYCLE
Sunlight has its own rhythm.
Power use can be planned ahead.
Understand how solar panels, a compatible charge controller, and BUKNUWO LiFePO4 battery storage work together to support your off-grid energy needs throughout the day and night.
This diagram illustrates typical energy flow in an off-grid solar system. Actual performance depends on solar conditions, battery capacity, system configuration, and connected loads.
DAYTIME
ENERGY FLOW
Generate Solar Power and Store Energy for Later.
During daylight hours, solar panels generate electricity. When solar production and system conditions allow, energy can supply connected loads and charge your BUKNUWO LiFePO4 battery through a compatible charge controller.
02 / YOUR OFF-GRID SPACE
Off-grid places,
life keeps its own rhythm.
What needs power in your off-grid space each day?
CABIN & TINY HOUSE
Life continues
after sunset.
You spend the day away and return to the cabin in the evening. Lighting, communication, and everyday devices often continue running after the sun goes down. Start with your daily routine, then plan daytime charging and nighttime storage.
Plan for this use
Devices that may need power
Lighting, networking, and phone or laptop charging. Add appliances such as a refrigerator when needed.
What to consider
Daily energy use, nighttime loads, occupancy patterns, and which devices must remain available during low-sun periods.
These are examples only. Check each device model against the complete system configuration.

Check battery status from your phone.
After connecting through Bluetooth, use the app to view state of charge, voltage, current, and battery operating status.
Bluetooth status viewing is not the same as remote cloud monitoring.Built-in management, with the right configuration.
The 200A Smart BMS provides electrical and temperature-related protections. System load capability still needs to be checked against the battery, inverter, and load requirements.
04 / PLAN YOUR DAILY ENERGY
Start by understanding
how much power you use each day.
Add the devices you plan to use, then enter their power, quantity, and daily runtime.
If you are unsure, leave the values open and verify them with your equipment list later.
My power loads
Use your actual requirementsPower calculation: W × quantity × daily runtime hours ÷ 1000. For intermittent loads such as refrigerators, use the daily energy figure from the energy label or your own measurement whenever possible.
05 / ONE SYSTEM. DIFFERENT ROLES.
From sunlight to powered devices.
Every part has a role.
Choose a component to understand its role and key matching considerations.
STORAGE
Store energy for later use.
Plan capacity around daily demand, usable energy, and your reserve target. Check charging, discharging, and connection requirements against the specific product information.
This is a functional overview, not an installation wiring diagram. The complete system also requires suitable distribution, protection, and connection components. Some functions may be integrated into the same device. View official matching guidance ↗
06 / BEFORE YOU CHOOSE
Before you start,
here are a few things to know.
From capacity and charging to equipment matching,
turn your power plan into something practical.
Is one 314Ah battery suitable for my use?
This depends on daily energy use, devices running at the same time, charging conditions, and your reserve target. Start with a device list, then check the battery and complete system configuration.
How much solar power do I need?
Consider local sunlight, seasonal changes, daily energy use, and how quickly you want to restore your reserve. The charge controller and battery limits also need to be checked.
How long will solar take to charge the battery?
Charging time depends on the starting state of charge, actual solar input, charging settings, and the energy used while charging. Estimate it from your specific system conditions.
Can I keep using my existing controller or inverter?
Provide the equipment model and specifications so the system voltage, charging settings, and power requirements can be checked. Compatibility needs to be confirmed item by item.
Can I add more batteries later?
Before expanding, check the connection requirements for the model and the capacity of the charging, inverter, and protection equipment. The final connection method should follow the product information and compatibility confirmation.
07 / START WITH YOUR NEEDS
Start planning your off-grid power
with your energy list.
Tell us where you will use the system, which devices you plan to run, and how your daily energy use is arranged. If you already have solar panels, a charge controller, or an inverter, include the model so it can be checked further.
