Talk to an Off-Grid Specialist Frequently Asked Questions What exactly is an "Essential Kit"? + An Essential Kit includes the core components needed to start building a reliable off-grid solar power system, including solar panels, inverter, battery storage, and system cabling depending on the selected configuration. How much power will this system actually produce? + On average, you can expect about 76,725 Wh (76.7 kWh) per day assuming 4.5 sun hours. This is typically enough to support a mid-sized home or property using roughly 2,300 kWh per month. Can I expand the system later? + Yes. The Sol-Ark 15K is parallel-capable, and you can easily add more OMO Freedom Series batteries or additional solar panels as your energy needs grow over time. Do the batteries work in cold climates? + Yes. The OMO 16kWh Lithium Battery features an integrated heating system specifically designed for reliable cold-weather performance and year-round operation. What is the benefit of Bi-Facial Solar Panels? + The included 550W Bi-Facial panels can capture sunlight from both sides. Depending on your mounting surface, such as light-colored rock or snow, you may see up to a 25% increase in energy production beyond the front-side rating. Is a generator required? + While not strictly required, the Sol-Ark 15K Inverter is generator ready. For full off-grid living, a backup generator is recommended during extended cloudy weather or heavy seasonal energy use. What kind of warranties come with this kit? + Warranty coverage varies by component. Solar panels, batteries, and inverters each include manufacturer-backed warranties designed to provide long-term reliability and peace of mind. Is shipping included? + Yes.
