1 3 5 2 4 6 When batteries reach 12.7V, the Smart Battery Isolator senses it, opens the solenoid relay to separate the battery banks, and turns off the status light. Another Unit that I don't see around anymore but was apparently quite good was a megatronics which was similar to the redarc in principal- solenoid operated by voltage sensitive switch but wasted less energy to hold the solenoid in. The Smart Battery Isolator is open and the battery banks are separated. Unfortunately I can't recall the brand or name of this unit. I do recall there was another unit on the market that used a changeover solenoid that only used power when switching from one state to another. The switching frequency is 150kHz and efficiency Battery Isolator Switch. You can always override the voltage sensitive switch if needed otherwise its a set and forget system. Every smart high side high current power switch is connected between +50V and. I personally am using a redarc because of it low tech base origons. If this stays on for ten hours you have lost 10ah. The solenoid whilst it is on will draw about an amp until the voltage drops and it cuts out. The Redarc which is a hybrid of an old technology solenoid with a a voltage sensing switch/surge protector on it. If you are looking for long periods between charging whilst you are camped you may wish to also evaluate the parasitic current draw these devices consume.

I can get the Projecta kit for $180 delivered, or the Piranha kit for $300 delivered, so Im just tossing up whether the extra $120 is worth it – as that goes a long way towards the extra battery !ĭo you guys have any thoughts, experiences or comments ?Ĭhoady Posts: 363 Joined: Thu 10:56 am Location: Kellyville, Sydney Power Consumption: 10mA (Standby)/ 330mA(Engage) / 0mA (Storage). The projecta has the ability to manually override the isolator so you can use the aux battery to jump start off. An isolator is used for allowing one charge source to charge multiple. Buy Car Double Battery Isolator Protector Auto Dual Battery Controller Smart Battery Manager Max to 300A Main And Secondary Batteries Are Automatically. Also, the Piranha one has a 5yr warranty, input for solar power for aux battery charging, and is rated to 180 amps (vs 150amps). Choosing between a dual battery isolator and a combiner depends on the application. They both come with everything you need to fit (heavy guage wiring, battery terminals etc), and the only real difference Ive been able to find by research/reading is that the piranha one uses electronic current limiting so no need for any extra in line fuses between battery and isolator (its one of their 11 reasons why piranha is 'better'). Cooler operating temperature compared to standard solenoid. Cost-effective protection against a flat battery. Im ready to buy a dual battery system controller and Im just trying to decide on either the 150amp Projecta kit or the Piranha dual battery system Microprocessor-controlled battery isolator designed for use in multi-battery applications.
