Knew I had seen before 🙂 Some history: > [@Victron Energy and The Thing Network](https://www.thethingsnetwork.org/forum/t/victron-energy-and-the-thing-network/25622): > > Hi, I am trying yo connect a solar energy system with a Victron Energy VE.Direct LoRaWAN - module thru the Thing Network to Victron’s VRM platform. I can’t seem to get connected. The blue led keeps blink “trying to connect” Has anybody else used TTN with VE components for a similar application? similar issues? I am supposed to be within reach of nearby gateways. What exactly is the right procedure? Thanks for your help, Carlos Also I see Tim (OP) already has experience with this:- > [@Mikrotik LoRaWAN Gateway](https://www.thethingsnetwork.org/forum/t/mikrotik-lorawan-gateway/23612/13): > > Hi @BoRRoZ, PV panel is 12V and 160watts. Inside box is: Victron Energy 12V PV MPPT controller. Victron Energy LoRaWAN monitor, goes via TTN to Victron Energy web portal. 12V 100Ah GEL deep-cycle battery. DC distribution and fuse panel. The LoRaWAN TTN base station and Mikrotik backhaul (this topic is about Mikrotik!) together consume a constant load of about 0.5amps = 6watts. Plenty of power for 8 months of year but marginal in North of Scotland during Nov/Dec/Jan/Feb due to periodic low-… @cultsdotelecomatgmai Tim, what was your impression and experience with the VE.Direct device? Worth trying one? How easy to get data to other dashboards if not using or not focussed on VE’s VRM? --- _[View the full topic](https://www.thethingsnetwork.org/forum/t/does-anyone-know-of-a-12-24-vdc-battery-bank-monitor/20028)._
