Description
The core advantages of this product lie in its powerful 100A MPPT solar charge controller, which efficiently captures up to 5000W of solar energy, significantly improving charging efficiency. With utility/generator dual input, it ensures an uninterrupted power supply under any circumstances. Combined with the intelligent management mode featuring customizable output priority (such as Utility Priority, Solar Priority, etc.), it effortlessly optimizes power usage strategies to maximize electricity bill savings.
In terms of battery compatibility, it seamlessly pairs with various lithium batteries, including LiFePO4, via RS485 communication, and features a unique PV/Utility activation function that allows easy recovery even from a fully depleted battery. Coupled with the equalization function, it effectively optimizes battery performance and significantly extends its service life.
The dual output design enables separate management for critical and non-critical loads. Built-in Wi-Fi makes remote monitoring easily accessible, while the detachable dust cover ensures stable operation in harsh environments.

Application
SANDISOLAR’s off-grid inverters are engineered to deliver robust and reliable power independence for a wide spectrum of applications where grid connection is unavailable, unreliable, or economically unviable. Our systems serve as the cornerstone of energy autonomy, empowering operations across diverse sectors.
Off-grid inverter systems are ideally suited for use in the following locations without grid access or with an unstable power supply: Remote areas (Mountains, ranches, islands, field workstations), Mobile power supply (RVs, boats, campers), Emergency backup power (Serving as a backup power source for homes or critical facilities to cope with sudden power outages).
