Magnum Energy ME-SSI Series Stacking Interface

Magnum Energy ME-SSI Series Stacking Interface, Allows 2 Units to Provide 120/240VAC, Fits MS4024 Only

The ME-SSI is a Series Stacking Cable Kit which allows two MS4024 inverters to be stacked together to achieve 120/240 VAC output. Series stacking is commonly used for well pumps, tools, motors, and other 240 VAC appliances.

When connected together in a series, the AC output of each inverter  continues to provide 120VAC, but the two 120VAC output waveforms are also phase locked and synchronized 180° out-of-phase from each other to provide 240VAC. This is commonly referred to as a 120/240VAC split-phase or as a 240VAC single-phase with a center-tap neutral, and is the same AC voltage configuration that most utility companies connect to houses. When inverters are series stacked, they must operate from a single
battery bank. A single battery bank configuration helps to balance charging and discharging. If your battery bank uses multiple battery strings (i.e., batteries connected together in series to provide the required DC voltage), ensure each battery string is connected together in parallel to form a single battery bank.

While inverting, a series stacked configuration allows you to operate 240VAC loads at twice the power that is available from a single inverter; and, the ability to provide the power of each inverter separately to operate 120VAC loads. While charging, a series stacked configuration allows the battery bank to be independently charged up to twice the power available from a single inverter; and if needed, provides back-up power for your 120/240VAC loads during a utility black-out.
