Tactical Edge Hybrid Power 3500W and 10.5kW systems optimize generator runtime and provide clean stable power 100% of the time. Sensitive electronics and medical equipment which could be damaged by the power surges inherent with generators can confidently connect to the Tactical Edge Hybrid Power 3500W system. The generator is turned on only long enough to recharge the batteries, then it is turned off – the batteries connected to the system are what powers the load.
