Need to build a 2 kW UPS for my server rack at my office. Eltek/Valere rectifiers for sure.
Not sure what inverter I will go with yet. Gonna run 100% inverter with a transfer switch in the event the inverter dies. But what is the best value for batts these days. I see Rolls at 13 cents per watt hour. Trojans for 16 cents (but they have ribs and a reservoir tip). Got a quote for absolyte types for about 18 cents. What else is out there? Truck starter batteries can be had for 10 cents but I doubt their longevity.
