Manual Isolatorsįor example, do you need to isolate a secondary battery purely for backup electricity? If so, you could probably get by with a manual battery isolator. The type of battery isolator you need depends on your electrical system and the reason why you need one. They help ensure you always have a power source, even if you accidentally drain your primary batteries. Whether it’s an RV, van, skoolie, boat, or off-grid cabin, these devices can be extremely useful. Thus, you can find battery isolators in nearly any off-grid electrical system. This can also help keep a fully charged battery handy as a backup.

➡ Dig into how to isolate your lead-acid and lithium batteries.Īnother common use for these devices is separating one battery from an entire electrical system when the charge gets too low. You can also use them to isolate two lead-acid batteries from one another to prevent one from drawing down the other. Where Are Battery Isolators Used?īattery isolators are used in any situation that involves multiple battery banks in the same electrical system.įor example, you can use them in vans, RVs, or boats to isolate the house batteries from the alternator and starter battery when the engine isn’t running. Many also use battery isolators to disconnect a battery that they are using as a backup. They’re needed in muti-battery systems where the batteries need to discharge or charge at different times.ĭepending on your system’s specific needs, you can use them to prevent both unintended and uneven battery discharge. To put it simply, these devices give users more control over their power systems. What Is the Purpose of Battery Isolators? Because our batteries charge so fast they can draw too much power from a conventional alternator. It also disconnects the power ever so often to prevent the alternator from overworking to charge our batteries. This unit will only charge the batteries when the engine is running and the voltage is safe. Here is an example of a Li-BIM isolator designed to work with our batteries. When the engine is off, the isolator quite literally isolates the second battery, allowing it to keep its charge. In the case of different battery chemistries, (like lead acid starting and lithium house batteries) you also do not want to connect them together. If the house batteried die then so will the starting battery. But when you turn the engine off, you don’t want the batteries to stay connected. Most often, however, these devices protect a secondary or backup battery from any unnecessary drain.įor example, when the engine is running, and the alternator is charging the starter battery, it’s also charging the secondary battery. It can disconnect a battery from a power system either for charging or discharging purposes.
What Type of Battery Isolator Do I Need?.What Is the Purpose of Battery Isolators?.I do get heat through the zone when another zone is circulating. (the zone valve controller on the zone next to it showed power on that wire when calling for heat)Īlso the pump showed power and ran when I used the jumper at the tstat terminals for this zone, however when i used the normal set up the power tester lit up only in time with the clicking. However, while calling for heat - and clicking - I didn't get power on the orange wire at all.

When I manually pushed in the switch with my screw driver tip, the panel started clicking. With wiring and tstat seemingly cleared I started to look at the zone valve controller more closely. So original wiring doesn't seem to be bad. I then bypassed the original tstat wiring with new wiring from thermostat to the zone valve (where it goes first) and also replaced the wire back to the control panel. I jumped the tstat terminals for the problem zone and there was no clicking, the LED lit up (which it hasn't for some time). When another zone clicks on, the buzzing and clicking in the problem zone stops. The buzzing and clicking is in the panel and seems to be in a cube (the first from the left next to an orange block) as it rapidly clicks (when calling for heat) the LED light lights up in time with the click.
I can say the Tstat wire goes to zone valve controller first with a return to the panel and also wire running between each controller so they are all in some way connected. I'm also not sure how to describe the wiring, I hope the pictures might help. Steve - I'm not sure how to check that my 120 is "clean" or check the transformer and aquastat.
This system is only for heat, baseboard and radiant, no AC. Re: 8 zones, We have a smaller second panel for the other two zones. I've attached some pictures below to hopefully help. Thank you for your responses Steve & HVACNUT.
