INTRODUCTION

   With electricity costs spiking all over the globe i expect more things to go wrong with electrical grids than ever before and let's face it, the last thing anyone wants is to end up having to replace computer parts and/or home appliances because of it. Well at least i certainly don't so to that end I've always had all my computers, TV sets and even refrigerators hooked up to UPS (uninterruptible power supplies) devices and yes i do realize this may sound as a bit overkill to some of you but spending 1/10th of the cost of any electrical device for something like that is well justified in my book. Still for office and business use where there are large server systems at play (among other devices) regular UPS models are obviously not the way to go and this is where the more advanced (at least usually) rackmount models like the Green Cell RTII UPS 13 1000VA come in.

   Green Cell is an idea created in 2013 as a response to the ever-growing demand for mobility. The team, originally founded by Paweł Ochyński wanted to create a brand, that will make our lives as easy as possible in a world dominated by mobile devices. From the very beginning, we have targeted Li-Ion technology as our specialization, and the first Green Cell branded products were laptop batteries and charges alongside with power banks.

   Unlike the PowerProof 2000VA model by Green Cell which i reviewed a while back (review here) which features line-interactive AVR topology with modified (or simulated) sinewave output waveform the RTII UPS13 line (currently available in 1000/2000/3000VA models) uses the more complex online topology together with pure sinewave output waveform. These two technologies give the RTII UPS13 line the ability to filter even the tiniest electrical quality fluctuations (especially ideal for areas with poor power quality) thus providing your equipment with clean and stable power (via AC to DC to AC conversion). Of course, the RTII UPS 13 family of UPS by Green Cell also provide overvoltage protection, are equipped with a front status LCD screen (rotatable), rear 80mm exhaust fan (active cooling) and 12V 9.0H AGM06 batteries (2 for the 1000VA model, 4 for the 2000VA model and 6 for the 3000VA model) and as for available connections we find 6 IEC320 ports (divided into two configurable segments), USB host port, RS232 serial port, EPO port (emergency power off - remote feature), two RJ45 ports and an intelligent slot (for USB and SNMP/ethernet cards). So, let's see what one of the top UPS models by Green Cell has to offer.
