In solar installation, the DC isolator is like a vehicle air-bag. You never know it really works until you need it. So it’s good to know that the IMO SI has now surpassed eight million installed units without a single recorded electrical failure. This incredible milestone really isn't surprising, considering the product carries all the most important approvals including UL508i, IEC/EN 60947-1, UL 60947-1, IEC/EN 60947-3, UL 60947-4-1, CE, RCM and CCC. In fact, the IMO SI solar isolator has been tested by some of the most rigorous examiners and OEM manufacturers in the world, passing with flying colours every single time. As ever, the SI range has a guaranteed arc suppression time of 3mS, in built arc cooling chambers, operator independent switching mechanism and Safe-Lock handle, making it one of the safest DC isolators available, no matter who uses it or how slowly they operate it. Since its launch in 2009, the SI range of TRUE DC isolators has set the benchmark safety standard for disconnection and isolation of the DC panel load in solar applications world-wide. Prior to the introduction of the SI series, AC modified isolators in multi-pole linked form were commonly used with all the performance and safety issues that such devices presented. Adopted as the standard by many of the largest solar equipment designers and installers around the world, the SI Series continues to set the benchmark in solar safety.
