I am testing out a Victron Phoenix 12v/1200VA for installation in my RV. The vendor had labeled the inverter as 1000W as additional information about the product.
The key use case is the Instant Pot Lux Mini. It's documentation say it uses a 700W Heating Element (plus a small amount of electronics). As 700W was much smaller than the vendors stated 1000W and because there is no motor or induction, I was confident it would work.
As part of the test bed, I have installed a Victron Energy VE.Direct Smart Dongle (Bluetooth) for monitoring purposes. I also have a Victron Shunt as part of the circuit and a clamp meter on the AC output side.
The good news is that it works. However, the system status information during my trial run worries me.
- Shunt shows current flow from battery: -65.36 Amps at 12.40V for a power of 811W
- VE.Direct (from the inverter) shows power delivered to the InstaPot: 1124VA and AC Output 120V with battery voltage of 12.28V.
- Clamp Meter shows 5.9 Amps between the Inverter and the Instapot
I understand there is no direct correlation between the VA output of the Inverter (1124VA) and the Inverter input power in DC Watts (811W). However, I am concerned that I may have been confused by the vendor describing it as 1000W Inverter.
- Instapot called out a 700W load.
- AC watt arithmetic of AMPS x Volts = 5.9*120 ~=700W.
My concern is that it would seem the inverter is barely able to handle a 700W resistive load. Interested if my concerns are my misunderstanding or if others have had similar experiences. Perhaps mine is misbehaving?
