OPTI-Solar

The Excalibur Plus series are designed to have access to dual input source: one is AC source from a grid, the other is DC source from a solar array.
This machine is a powerful all-in-one solution, delivering unsurpassed clean true sine wave output power.
The built-in 3-stage intelligent charger automatically charges any type of batteries without the risk of an overcharge. The compact and modular design makes utility interactive installations easier and more cost effective.
It is a high quality product that offers the best price-performance ratio in the industry.
