Quick Answer
Sol-Ark hybrid inverters are ideal for rural areas where off-grid power systems are necessary. They offer whole-home backup power and off-grid capabilities, making them suitable for remote homes, cabins, and recreational properties. These inverters can also be used in grid-tie applications with a battery bank for energy storage.
Whole-Home Backup Power
Sol-Ark hybrid inverters, particularly the 12K and 15K models, can power entire homes during grid outages. To achieve this, a suitable battery bank is required. A bank of 24-48 12V deep cycle batteries with a total capacity of 20-50 kWh is recommended for a 3-5 bedroom home. This setup allows the Sol-Ark inverter to charge the batteries during the day and provide backup power during the night or when the grid is down.
Off-Grid Capable Systems
Sol-Ark hybrid inverters can operate in off-grid mode, making them suitable for remote properties without access to the grid. In this setup, the inverter charges the battery bank from a solar array, wind turbine, or generator. A suitable solar array size can be estimated using the following formula: (Total daily energy demand in Wh) / (Peak sun hours per day) = Total solar array size in Watts. For example, a 5 kW solar array can provide 18 kWh of energy per day in a location with 4 peak sun hours per day.
Battery Monitoring and Charging
Sol-Ark hybrid inverters come with built-in battery monitoring and charging capabilities. They can charge and discharge the battery bank safely and efficiently, extending its lifespan. The inverter also provides real-time monitoring of battery state of charge, voltage, and current, making it easier to optimize the system performance and identify potential issues.
