Wireless Inverter Control Remote

Re: Wireless Inverter Control Remote

Also, you need the remote to operate from, and switch, 12 volts DC...

Something like this (6 amps, 12 vdc, 300 foot range?) powering a big-old relay.

Re: Wireless Inverter Control Remote

I don't know whether to believe them or not--but they said 300' range for the wireless relay. From the link a customer comment:

A customer from Asheville, NC
Better than I expected
I have used this remote for three months around my farm. I use it in conjunction with auto power window motors to control stock gates, chicken house door and lights. The range is at least 300 feet free air and through two walls. I have ordered and received another of these units for a neighbor and the frequencies are different. So I will get another for myself. I don't know how many frequencies sets there are, but there is a code on each box. The unit has been consistent and reliable.

I have no idea if this is a good/bad unit--It was just the first hit in a Google search for "12 vdc remote control".

There are lots more out there... Regarding the Big-Ol' Relay. The standard version probably can take upwards of 1 amp for the coil. I did not look through the BlueSea relays in detail--but it appears that some of them are Latching types so that you will not be wasting as much power to "hold them on".

For example:

Power Consumption - inrush max, 130ms

• 3.80 Amperes

Power Consumption - Holding

• 12 Volts -0.13 Amperes
• 24 Volts - 0.07 Amperes

This other model (PDF Download flyer) requires no current to hold ON or OFF, just energy to change state... However, it looks like it needs both a Normally Open and a Normally Closed contact (one leg powers the "ON" function and the other leg powers the "OFF" function). You could get a small signal DPST relay to provide the translation if needed (at the cost of slightly more power wasted).

For "off the wall" solar stuff--I keep looking to boat suppliers (Like BlueSea) for those accessories.

Re: Wireless Inverter Control Remote

Here is another company that offers bi-directional switches that may work fine for the BlueSea latching relay (and 500-900 foot range). The receiver itself can handle 80 amps directly. They have smaller units with a key fob--but that range is shorter (and the relay is lower current).

There appear to be quite a few options out there.

Doesn't the remote need a RF transmitter instead of a manual switch. Trying not to confuse myself here.

I am not sure what you are asking here... There is an RF Transmitter and an integrated RF Receiver/Relay Module. You then need a second High Current Relay (like from BlueSea) to interrupt your heavy current flow.

So: The remote is to connect an in/out single line (wire) and the RF transmitter is for using its magnetic lock to switch on/off via remote control ?

Maybe I am misunderstanding your requirements?

I thought you wanted a simple one or two button RF transmitter in your home that could turn on and off 100 amps of DC back in the barn using an RF Receiver/Relay between the battery bank and Inverter.

Do you want to control the RF Transmitter electrically/remotely itself?

The Latching vs Non-Latching 100+ amp relay is to save the 1-6 watts or so that non-latching high current relays typically consume when energized.

The latching relay only consumes power when turning on or off. But requires a bit more complex circuit to drive its two controller wires instead of the one for a non-latching relay.
