The Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.
Features
New: intelligent battery monitoring to prevent unwanted switching
Some battery combiners will disconnect a battery in case of a short but high amperage load. A battery combiner also may fail to connect a large but discharged battery bank because the DC voltage immediately drops below the disengage value once the batteries are connected. The software of the Cyrix-i does more than simply connect and disconnect based on battery voltage and with a fixed time delay. The Cyrix-i looks at the general trend (voltage increasing or decreasing) and reverses a previous action only if the trend has reversed during a certain period of time. The time delay depends on the voltage deviation from the trend.
In addition, four switch timing profiles can be chosen.
12/24 V and 24/48 V auto ranging
The Cyrix-i automatically detects system voltage.
No voltage loss
Cyrix battery combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.
Prioritizing the starter battery
In a typical setup the alternator is directly connected to the starter battery. The accessory battery, and possibly also a bow thruster and other batteries are each connected to the starter battery with Cyrix battery combiners. When a Cyrix senses that the starter battery has reached the connect voltage it will engage, to allow for parallel charging of the other batteries.
Bidirectional voltage sensing and power supply from both batteries
The Cyrix senses the voltage of both connected batteries. It will therefore also engage if for example the accessory battery is being charged by a battery charger.
The Cyrix-i has a dual power supply. It will therefore also close if the voltage on one battery is too low to operate the Cyrix.
In order to prevent unexpected operation during installation or when one battery has been disconnected, the Cyrix-i will not close if the voltage on one of the two battery connections is lower than 2 V (12 V battery), or 4 V (24 V battery) or 8 V (48 V battery).
Parallel connection in case of emergency
The Cyrix can also be engaged with a push button (Cyrix remains engaged during 30 s) or a switch to connect batteries in parallel manually.
This is especially useful in case of emergency when the starter battery is discharged or damaged
Reasons to buy your Victron equipment or off-grid setup from us
- For safety reasons, 12v and 24v systems have been the mainstay of powering boats for half a century or more so we are well aware of the both fitting and using these systems.
- Everything we know about power and charging from boats is just as applicable to van life or off-grid installations.
- Accurate availability and realistic delivery estimates.
- We have sold thousands of Victron Units as well as everything needed to install and connect.
- If for whatever reason you have a problem, our strong after-sales service will make sure you are looked after and we will drive through any warranty cases as quickly as possible for you.
- Exceptional customer service is our top priority, reflected in our 5-star reviews.
We are excited by the technological improvements in this sector and know how modern lifestyles mean ever-increasing power demands, whether at home or away for your hobby. Having used and worked with this technology as it has emerged, we are not just ‘jumping on the bandwagon’, but sell this as an integral part of helping our customers make the most of their time on their boat or van. This makes us the perfect choice to advise on and supply your power system regardless of where the installation is going.
