The right size depends on your energy consumption and location. Our pre-configured kits (e.g., 10kWh, 15kWh) are a great starting point. For a detailed calculation, we recommend using our onlineOff-Grid System Sizing Calculatoror consulting with one of our experts. You'll need to list all your appliances, their wattage, and daily usage hours to determine your total daily Watt-hour (Wh) needs

Yes. While many of our entry-level kits are based on scalable 12V architecture for simplicity, our systems are designed to be expanded. You can easily series-connect our LiFePO4 batteries to create 24V or 48V battery banks, which are more efficient for larger off-grid homes and allow for the use of higher-power, lower-cost inverters.

Absolutely. Our larger inverter options (3000W and above) are capable of starting and running well pumps, refrigerators, and even small air conditioning units. The key is to have a sufficiently large battery bank (e.g., 10kWh+) to support the high energy draw and a powerful enough inverter to handle the startup surge.

A well-designed off-grid system accounts for this with "days of autonomy." This is why we offer large battery capacities and highly efficient MPPT charge controllers. For extended bad weather, we recommend having a backup charging source, such as aRenogy DC-DC Chargerconnected to a backup generator, to ensure your batteries stay charged.

The complexity varies with system size. Connecting the Renogy components (batteries, inverter, charge controller) is straightforward for a competent DIYer.However, we strongly advise that the high-voltage AC wiring from the inverter to your home's breaker panel, as well as the grounding and lightning protection, be performed by a licensed electrician to ensure safety and compliance with local codes.

Yes. Our Renogy LiFePO4 batteries are completely maintenance-free. Unlike lead-acid batteries, there is no need to check water levels or perform equalization charges. Simply install them, and the built-in Battery Management System (BMS) handles everything for optimal performance and longevity.

Yes, scalability is a core design principle. You can start with a base kit and later add moreRenogy LiFePO4 batteriesin parallel, install additionalsolar panels(within the charge controller's limits), or upgrade to a more powerfulinverter. Our components are designed to work together seamlessly as your energy needs grow.

While not always mandatory, we highly recommend it for true energy independence. A backup generator, integrated via an inverter-generator port or an automatic generator start function, provides peace of mind. It ensures you have power during extended periods of poor sunlight or if a system component requires service.
