Victron's Phoenix Multiplus has all features of a sine wave inverter and charger in one compact enclosure.
UPS functionality: seamless transfer from external AC to inverter supply.
A unique AC power management system will prevent overload of a limited AC
source. First, battery charging will automatically be reduced when otherwise
an overload would occur. The second level will boost the output of a
generator or hook-up supply with power taken from the battery: where
peak power is often required only for a limited period, the Victron Phoenix MultiPlus
will make sure that insufficient hook-up or generator power is immediately
compensated for by power from the battery.
Scalable: any number of units can be paralleled in single phase, split
phase and three phase configuration.
Size (mm): 375 x 214 x 110 Weight: 10 kg

Why we rate it GREAT STUFF!
Once we decided we would take with us mains-powered equipment like toaster,
electric kettle, television, computer, Remoska electric cooker (love
it) there didn't seem much point in lugging all this about if we didn't
always have mains power - and of course a hook-up is not always available.
The MultiPlus's powerful inverter (we chose the 1000 watt version - continuous
but up to 2400 watts peak) can power all of our equipment, with the highest
quality clean sine-wave 230v supply.
But that's only part of the picture. If we do have a hook-up but of only limited
amperage (say 4 or 6 amps) or if we use our small Honda EU 10i generator
(900 watts continuous, peak 1kw) but we switch on too many appliances
for the available supply, the MultiPlus's inverter PowerAssist function
kicks in automatically within milliseconds, and supplements the hook-up
or generator supply. This means that a generator can be sized at much
less than potential loads, saving costs, weight and bulk. For instance
we have available 1.9 kw continuous or 3.4 kw peak. Unplug the hook-up
while a computer is still running? No problem, the inverter takes
over so fast that it serves as a UPS (Uninterruptible Power Supply) .
An optional remote control panel for the MultiPlus also allows us to dial-in
a maximum value for the hook-up supply: the MultiPlus then protects against
drawing a higher current which might trip a cut-out on the campsite supply.
You might have noticed that so far all of this amounts to a hammering for
our hardworking leisure battery which is soon going to run out of charge
at this rate. This is where the MultPlus's sophisticated charger takes
over. Whenever it is connected to an external 230 v supply - hook-up
or generator - the MultiPlus constantly monitors how much of that external
supply is not being utilised to run appliances and the surplus
is used to re-charge the battery. The MultPlus has a very large charging
capability: up to 50 amps (for our 1000 watt version) which in practice
is too much for typical motorhome battery installations; however a maximum
charging amperage can be programmed into the unit to match it to your
battery size; this is done before the MultiPlus is despatched to you
(or you can do it yourself using a laptop computer but you would need
to buy the optional interface connector).
Like everything else about the MultiPlus, the charger is designed to
optimise the capacity and service life of your battery. It's multistage
charging regime can be set to cater for all the types of batteries commonly
used in motorhomes.
