Hi, and how do I change my router information.

Perfect

Thanks .very informative

I am hoping I can get a response install 3 of these inverters ran 58 volts DC to them battery side did not have solar hooked up or grid hooked up as soon as I closed the switch on the batteries I blew the exact same igbt I also pre-charged the system with an inline resistor I'm repairing the igbt now and I'm very hesitant to hook the batteries back up the company growatt is giving me the runaround that's why I am fixing it myself I asked them what the max voltage was on the battery side they could not answer I am using lithium ion why would hooking up the batteries below this igbt?

Hola, si me uno al grupo obtengo asistencia via whatsapp? gracias

Hello. can U sell a full set of component to replace ? By mistake i short PV - to inverter body. For sure i kill all 140N08, thanks to U i also know what to check more.

Great video, thank you. I have 5star 5kw. inverter. On main pcb air flow direction arrow shows upwards. But fans suck air down, against natural invection of warm air. Will it be safe to physically turn fans around to blow upwards, I read on inv. forums that inverter runs much cooler then.

I run a repair shop and watch your videos and learn alot from this channel. Yesterday a Growatt solar inverter model: (SPF 5000TL HVM-WPV) came into my shop by customer and it has some wierd fault when the AC is plugged in and the AC charging current is greater than 20Amp the inverter goes into error 08. Remember this happens when PV is not present. I have upgraded the firmware using ISP tool but the problem still persist. I will be very thankful to you if you guide me?
