This means the Orion shuts down after 1 minute, then will wait for the duration of the START timer (default 2 mins) before attempting to charge again…. The issue I have is that the Iveco alternator seems to happily go below the shutdown voltage for 2-3 minutes despite the engine not being shut down. (During this minute charging will occur unless it goes below the Input Voltage Lock-out value in which case it will stop immediately.) Victron assume that if the starter battery voltage is below the configurable Shutdown voltage for 1 minute then the engine is off. Victron seems to have hard coded this to be 1 minute. The second timer is used to detect shutdown….

No issue with this timer - I understand it’s purpose and value I have read Victron’s description of shutdown protection - there are two timers involved - the delayed START timer - which is user configurable - is there to ensure leisure battery charging is delayed until the vehicle battery has a chance to recover from starting the vehicle’s engine. with the previous Sterling B2B it worked rapidly and flawlessly to charge our leisure batteries. Default: 13.3V (Smart Alternator) and 13.8 (Regular I think the alternator is man enough…. The energy used during starting must be replenished to ensure that the starter battery remains properly charged.

To ensure that the starter battery is recharged after starting the engine, charging of the auxiliary battery is delayed during this condition. If you are using the smart alternator option in settings, then it should allow a lower voltage.ĭelayed start voltage (Vstart(delay)): Smart alternators can generate a lower voltage when the engine is running, therefore a lower start level is necessary for these systems. Have you tried using a different alternator type to see if the situation changes? Or set your lockout voltage values.

See the link about shutdown detection.Įither your alternator is not man enough for the charge amps for the system plus charging 3 batteries (hence the low voltage in the system) or you have number of smaller issues making one big problem.įor example, a combination of a starter battery in poor condition and often the voltage drop over the wiring to the orions, making the voltage detection see a lower voltage.

Orion DC-DC Converters not your engine starts the alternator would ramp up the voltage, this would signal the orion to start. If I change the engine shutdown too low then it simply won‘t detect a real shutdown.Īny suggestions? Is there a way to change the engine shutdown from a 1 minute timer to a 5 minute timer or some other solution?Īt the moment I consider the Orions to be an expensive mistake.

makes little difference as the alternator is down at 12 v for longer than a minute and then the engine shutdown detection kicks in. I have already set Input lockout down to 11.8v off and 12.2v on…. I used to have a Sterling 60A B2B charger that worked flawlessly (although it died due to the cooling fan getting dust in it and halting the fan) I had assumed that the Victron beasts would be at least as effective as the Sterling and not have the cooling fan issue. End result is that the Orion seems to think that the engine is in shutdown mode the majority of the time and is completely useless for charging the batteries. Starter often sits at about 12v for several minutes and then occasionally goes up as far as 14v. The issue seems to be that the starter battery voltage goes very low for significant periods of time while the engine is running. I am using 2 x 30A Orion (non-isolated) to charge 2 x 200aH Victron lithium batteries… Or rather I am failing to charge the batteries. I have a Iveco Daily Euro5+ van with a smart alternator.
