Description
Created with quality in mind, the Victron Energy Phoenix Inverter VE.Direct 250VA – 500VA  range has a huge variety of applications. Victron has created a true sine-wave inverter with peak efficiency and great performance. A top-of-the-range product with a compact size, the Victron Energy Phoenix Inverter VE.Direct 250VA – 500VA is capable of supplying power, problem free, to any load.This Victron Energy Phoenix Inverter VE.Direct 250VA – 500VA comes with a VE.Direct interface port, allowing you to have even more control over your device. Just connect it up to a computer or Apple/Android mobile device to configure settings and receive updates that will help you run your system with ease and control.
Recently released, is the new Phoenix Inverter VE.Direct firmware version v1.03, which besides a few internal changes, has a major new feature – the addition of Dynamic Cut-off. Some of you may know it from Hub-4. What it does is this: instead of using one fixed battery voltage as the low battery shutdown level, it also looks at the battery current. This makes sense, as we all know battery voltage drops when putting a load on it; caused by the internal resistance of a battery bank.
Previously you had to pick one voltage and enter that as the low voltage shutdown level, which would never be right. For example setting it to 10.5 V will do fine while powering significant loads. However, when left like that for a couple of weeks, without high loads, the inverter will keep on drawing power from the battery until it hits 10.5V, by which time a lead acid battery will have suffered damage as it has now been discharged too deeply. And putting it at 12V, which would be a nice cut-off value for a battery without load, won’t work either because as soon as you do put a load on the inverter it will shut down almost immediately.
Dynamic Cut-off fixes this issue by using not only the battery voltage, but also the discharge current to determine the battery empty condition.
During configuration, choose the battery type and enter the capacity of the battery bank. The type is necessary to select the right charge curve as not all batteries have the same internal resistance. The capacity is necessary because the current drawn needs to be put in perspective in relations to the size of the battery or battery bank. Perhaps to understand this more easily imagine a huge battery bank; a football field full of batteries. Now picture one small 250 VA inverter in the corner. Even loaded to full power, this inverter will not make the voltage of that huge bank drop one iota, as the load is negligible compared to the size of the bank.
