SENS MicroGenius S2 Battery Charger

Batteries & Chargers

12-120VDC mid-range switchmode battery charger system. 20-50A output using paralleled MicroGenius 2 modules. Optional redundancy, dual outputs, circuit breakers. For mid-size to large generators.

Overview#

The SENS MicroGenius S2 fills the gap between the standalone MicroGenius 2 (6-25A) and the high-current S4 (25-100A). It uses the same proven MicroGenius 2 switchmode modules in a paralleled configuration, delivering 20 to 50 amps at 12-120VDC with integrated circuit breakers and optional redundancy.

The S2 is the right choice for mid-size generators (500-1000 kW) where the starting battery demands exceed what a single MicroGenius 2 can deliver, but the full S4 system would be oversized.

Our service experience#

We spec the S2 for mid-size commercial generators where dual independent outputs or circuit breakers are needed. The modular architecture means field service is straightforward — if a module needs replacement, it's a MicroGenius 2 swap, the same unit we carry on every service truck.

Frequently Asked Questions

What is the MicroGenius S2 and when should I choose it?
The S2 is a multi-module system using paralleled MicroGenius 2 chargers, delivering 20-50A output. Choose the S2 when your DC current needs exceed 25A (the MicroGenius 2 maximum) but stay at or below 50A. It also adds circuit breakers and supports redundant or dual independent outputs — features the standalone MicroGenius 2 doesn't offer.
How does the S2 compare to the S4?
The S2 handles 20-50A, the S4 handles 25-100A. Choose the S4 when you need more than 50A, aided surge suppression, or 2+ independent battery banks. For mid-size generators in the 500-1000 kW range, the S2 is typically the right fit. For large-frame generators above 1000 kW, step up to the S4.
Does the S2 support redundancy?
Yes — the S2 can be configured with redundant outputs or dual independent 25A outputs. Because it uses independent MicroGenius 2 modules internally, a single module failure doesn't take the entire charger offline.
