Hyundai HiS-S405YH(BK) Solar Panels

Premium Performance with Bifacial Technology

The Hyundai HiS-S405YH(BK) modules offer enhanced performance thanks to bifacial monocrystalline half-cell technology, which captures reflected light from the ground and increases overall energy production by up to 25%. A sleek black-on-black finish makes them aesthetically ideal for rooftops. Built to withstand high wind and snow loads, these panels are certified for durability and long-term performance.

EG4 12000XP 48V Off-Grid Inverter

Pure Sine Wave Split Phase Power for Demanding Off-Grid Applications

The EG4 12000XP is a split-phase, all-in-one 48V DC off-grid inverter delivering 12,000W of continuous power output and up to 18,000W of surge capacity. This inverter is designed to power entire homes or remote properties and includes an integrated MPPT solar charger (max PV input: 500VDC), Wi-Fi connectivity, and parallel stacking for up to 10 inverters (120kW total). It also features generator auto-start and multiple battery communication protocols, making it highly adaptable.

EG4 14.3 kWh Indoor Wall Mount Batteries

High-Capacity Lithium Iron Phosphate Energy Storage

Each EG4 14.3 kWh battery offers 51.2V of storage using safe and long-lasting LiFePO4 chemistry. With an expected lifespan of 8,000+ cycles and a 15+ year design life, these batteries are perfect for off-grid homes or backup systems. The integrated BMS protects against overcharging, undervoltage, and thermal issues, while a built-in heater supports cold-weather charging.
