ERC-12-15 Emergency Relay
The Emergency Relay/Charger is a device for assuring immediate backup power to communications equipment in the event AC power is temporarily lost to the power supply or the supply fails. In addition, it will allow the power supply to act as a “trickle” battery charger without any additional modification.
When loss of DC voltage is sensed by the ERC, it employs a fast-acting S.P.D.T. relay to automatically switch the equipment’s DC input over to a standby battery to allow continued operation. When the power supply is returned to service, the ERC disengages the battery and puts the supply back online to provide DC voltage. While the power supply is operating normally, a small portion of the output current is directed to the battery to trickle-charge and maintain it at full voltage. (Note: Battery float voltage will be maintained at .7 volts lower than the power supply voltage.)
Note: If the power supply is down for an extended period, the backup battery may become significantly discharged while powering the radio. When the supply returns to service, the trickle charge rate of the ERC may be insufficient to restore the battery to full charge in a timely manner. In the event this occurs, a supplemental charger may be necessary to bring the battery to full charge.
Installation
Select a suitable location as close to the battery as possible where there is no likelihood of accidental contact and shorting of the terminals. The ERC may be mounted vertically, horizontally, or even upside-down, if necessary, without affecting its operation. Two # 10 sheet metal or wood screws will be needed. Mounting on a metal surface is acceptable as the inputs and outputs are isolated from the mounting bracket.
Note: If the battery is stored in an unventilated enclosure, it is not recommended that users mount the ERC within the same enclosure. As with any relay, it should not be in an area where there may possibly be battery gases or any other potentially explosive gases present.
Wiring
The wiring should be as direct as possible. Ensure that the battery posts are free from corrosion. Determine the correct gauge wire using the information below. The wire length is the total length of the run (ERC-to-Radio + Power Supply-to-ERC) or (ERC-to-Radio + Battery-to-ERC), whichever is longer.
Use the provided crimp ring lug connectors to secure wiring to the ERC. Models ERC-12-15 and ERC-24-15 are provided with yellow plastic terminal covers, which must be reinstalled after wiring to prevent accidental shorting.

Arco A 275 alternator is almost a perfect fit on a yanmar 4jh3e. Installed with balmar pulley kit . Easy install and fast charging .n more belt dust covering everything.
3@405 watt rec panels on top of Bimini with 2@ Hyundai bifacials on top of Atlantic tower. 1x2 “ anodised aluminum used for supports . Each panel has their own mppt charge controller due to the amount of Shade on my sailboat.panels are providing a lot of power.
Instalation instructions where easy to follow.
The Zeus can be adjusted with the app to adjust the charging parameters.
Enclosed picture of gx device show a lot of solar going into batteries so the Zeus is providing enough amps to max out 300 amps going into batteries. If I was using more ac devices the alternator will increase output . Temperature sensor included with Zeus allows it to reduce output until alternator cools down.
Mabru air conditioner is great improvement from my old model. Cools boat down quickly. Easy install. I run this 17k unit of my 12/100/3000 ,victron invertor. Sometimes the solar panels will provide enough power for air conditioner ,2 fridges and all other loads.
Modular Rainman watermaker installed in separate locations. The motor and pump fit well under nav table seat ,membranes fit below forward bed. I made 80 gallons of water whilst motoring into port royal sound s.c. My victron 12/120/3000 invertor had no trouble running it .
The water produced was 200ppm. About the same as my city water filtered through Brita pitcher.
