Question

How to attach a solar inverter so it can be seen on wifi

by pwhipp / November 23, 2014 7:13 AM PST

I've recently added solar power to my office roof and I'm trying to set up monitoring for it.

My office has a repotec n-way switch which connects my PC and printer to my home network using a wired connection to a DSL-244N D-Link router/modem.

I connected the solar inverter to the hub and I can ping it and log data on my office PC using the address I entered into the inverter (192.168.1.228).

However, when I'm using the wireless network provided by the router/modem, I cannot ping the 192.168.1.228 address so I can't get the monitoring software on my smartphone to work.

It is not practical for me to cable directly from the inverter to the router/modem so I have to plug the inverter ethernet cable into the switch.

How can I configure the router (or system) so that devices on the wireless network can see the inverter?

Many routers have a firewall.

Firewall can't be disabled but...

Thanks for your response, Bob.

On the d-link router modem (DSL-244N), the firewall cannot be disabled Sad

As I understand it, the firewall would not be the cause of this problem because the inverter and the other computers are all on the local network, but to verify, I added my smart phone as the DMZ computer which according to the d-link documentation removes it from the firewall restrictions. It is still unable to ping or receive data from 192.168.1.228.

I have tested access using ping wired at the router and wirelessly using a Linux laptop and I can ping the inverter so this problem is not a network issue as I first thought. For some reason the monitoring application on the phone is not working.

Sorry to have raised this as a networking problem.

Sounds like a defect.
by R. Proffitt Forum moderator / November 24, 2014 6:50 AM PST

If there was some configuration issue, well maybe someone has a guest network but with just what I read here, there is a defect in some product. Again, there are CLIENT ISOLATION, Guest networks and more but can't disable the firewall? That's a first. I'll take your word on that.
