What’s the right device to take a 240v AC split phase (L1+L2 hot, Ground) and convert it to 12v DC (50A/600W max)?
Can the Phoenix IP43 charger handle split phase AC as an input, or does it require L1 Hot + L2 Neutral, Ground?
Is there a compact solution for this, similar in size to an Orion-TR DC/DC converter or a SmartSolar MPPT, without requiring a large transformer like those in MultiPlus units?
What kind of battery voltage are we talking about on the Multi? if you use one ?
Or is it just for charging on a split phase system ?
Why don’t you try to get Victron Phoenix 12/50 (2+1) 120/240V – PCH012050001 90…265v AC
You can connect it to 120 or 240v
That’s my question. Can I? Can that unit handle split phase AC (L1+L2+G) or is it only compatible with single phase (L1+N+G)?
Not all 240v power is the same. L1+L2+G != L1+N+G, even though both are ‘240v’ systems. Some hardware that indicates a range of supported input voltage are designed to handle either scenario and some hardware requires one or the other.
Charging a 400AH 12v battery system from a 240v split phase AC power supply (L1+L2+G)
Consult the manual or ask a victron dealer
This question often arises when using a multis for 230V L-N - on a split phase 120/120
Here, however, the use of the earthing relay is one of the reasons why this is not possible.
However, since you ONLY need a normal 230V supply and also have a functioning protective earth conductor, this works perfectly.
In the 120/240V split range, normal ‘European appliances’ are also used in the domestic sector. The voltage is slightly lower, but as they are switching power supplies, you can use them as normal.
However, always protect with a suitable 2-pole circuit breaker or residual current device.
As the PCH012050001 is only an isolated charger i don’t see any problems, but, as i said, ask a victron dealer.
Always ask the dealer !
