I plan on running up to three 12|12 30A Non-Isolated DC to DC chargers in parallel in one of my systems and I just want to verify that the way I'm doing it is safe.

I plan on running 2awg cable from the alternator connection to a "LittleFuse" 1-3 way fused distributor (image attached), then from the distributor to each charger via 6awg cable. I'm not certain stepping down from 2awg to 6awg is the best idea, but if that's ok, please let me know.

Hello all,

I use the battery isolator 120-2 AC to charge redundant batteries (24V, 150Ah each) with an alternator. To ensure the excitation of the alternator, the isolating diodes have this special Energize connection.

According to the datasheet, the Energize is a current-limiting connection for start-up excitation. What does current limiting mean? How much current can flow max.

And does this current only flow to the input connector into the alternator or can the current from Energize also flow to one of the output connectors?

The line to the Energize connector is fused with a 6A fuse. But it keeps blowing out. Therefore the questions.

As an additional note to Victron, please provide more info in the datasheets.

Thanks and greetings

When connecting an Argofet Isolator to a battery bank with paralleled batteries, do you use one isolator output for the entire paralleled bank, or use multiple outputs, one for each battery In the paralleled bank? On my boat, I have a starter bank with a single group 34 battery, and a house bank with two identical group 31 batteries. I’m believe I need a two bank isolator but just wanted to confirm that I don’t need a 3 bank isolator. Thanks for your help.

Hi Guys,

Cant for the life of me figure out what’s going on here. Shunt is showing that the Orion is drawing charge and the battery % is dropping while it’s running instead of charging

Thanks in advance for your help.

I don’t have a smart alternator. vehicle 2018 Citroen relay.

Shunt definitely wired the corrected way round and all readings are normal.

checked that the input and outputs are definitely correct.

Victron Blue Smart working perfectly and showing positive values while charging.

checked the earths and they are both linked

the breakers do have a battery and load side written on them. battery side is wired to starter battery for both of them.

Similarly, the two + terminals might also be tied together (as long as its either-or but not both)?

Hello, is it possible to operate two converters in a parallel relay to provide a charging current of 80 amps in total, the system consists of a 100 ampere generator 24 volt system?

I want to have a common DC bus for powering a system. We already have a battery bank that has been working for a couple years and we are adding a new battery bank for expansion. Can I include an Isolated Orion DC-DC at each battery bank prior to the Bus to couple all the loads in one bus?

Hello,

I have 2 ways to charge my leisure battery, one via shore power and one via the car batt.

Can i connect both chargers in parallel to the leisure battery? Should i install a relay to make sure the not-operating charger is isolated from the circuit?

Can i consider the orion smart dc dc charger as an isolator between the car and leisure battery? Or should i put a physical relay/isolator as well?

If i use the ’engine running detection’ can i consider the car battery isolated from the leisure battery when the engine is off? Or is this too much trust in the system?

Thanks for the help

I have a Buck Boost 25A 12V DC (12.5A 24V DC) DC-DC charger (Alternator to battery charger / isolator and several other terms) installed in a Sprinter custom motorhome to transfer amps from the 180A 12V alternator to a 24V lithium coach battery. It's working great for years but wish to increase charging amps. I prefer BT vs. USB so am considering adding an Orion-Tr rather than another Buck Boost. I wish to know if either differing chargers would "care" or whether they would both simply function the same?

For the super advanced techs, I'm also curious if it's more efficient to run in series to achieve 24V vs. program conversion from 12V to 24V in parallel?

I am new to 12V systems and am currently specing out / purchasing components for my 2020 4x4 sprinter conversion power system. I have purchased 2 x 12/12 30A Orion-Tr Isolated smart units since I am looking to obtain 60A charging capabilities. I am building a 12V 400Ah battery system. I see the fusing recommendations are 60A at the starter battery and 60A at the auxiliary battery side, this is however in the case of having a single 12/12 30A Isolated unit.

What would the fusing reccomendation be for two units in parallel? do I fuse / circuit breaker them separately effectively having 4 fuses configured? If not I would appreciate any documentation links or schematics I can refer to. Any input is appreciated!

So far I am using Blue Sea Systems components for Bus Bars, Battery Switches and Circuit Breakers.

In an installation of two panels in parallel with the victron smartsolar MPPT 100/50, is there a way to control the presence of the panels by VE.direct (RS232)?

My latest downloaded data is timestamped (Europe/Berlin +01:00).

All previous data has been timestamped (Sydney +11:00) or +10:00 depending on Daylight savings.

Is there a way I can set it to behave as previously?
