We have a radio site that has 3 x Pylontech 3000 batteries connected to a Multiplus 48/1200/13 Inverter Charger and a Venus GX. Under commissioning of the site no AC was present and the batteries have now gone flat. So the Inverter charger has a solid LED alarm which will be as a result of the pre alarm for battery low being activated. The site is now has an AC connection and Inverter charger is starting to recharge the batteries but the Venus GX is making a loud beeping noise every 1 second or so. What is causing this and how do I stop it? Is it as a result of the low voltage alarm being activated on the Inverter charger. We can't remotely connect to the Venus GX device as the radio equipment is off due to the batteries being too low. Thanks Alistair.
