What is the maximum wire size it accepts?

10ga is the maximum size. This is an awesome device. I'm very happy with it.

Will this mppt charger connect to a venus gx via ve.direct port to monitor through the victron vrm portal? or do i need one with a ve.can port?

Yes it will work with the ve.direct port that’s what I currently have for this connection.

Can I use a propane generator with this controller to charge 24Vx300ah battery bank (2x 12V in series) ?

Controller will feed the battery from your PV. If it sees extra voltage from your generator/converter it will go to float charge. It’s not meant to take any AC directly from a generator if that’s what you meant.

will this accept #4 AWG cable?

I don’t think so. I used oxygen free copper 8 gage on mine and wasn’t much space left so I really doubt it’ll accept 4 Gage (AWG).

Excellent product and a great price. Still works flawlessly after one year of service and no issues.

Attenzione il prezzo sembra essere buono ma questo è dovuto al fatto che non è la versione VE.Can del regolatore di carica . Potete trovare la versione VE Can allo stesso prezzo o addirittura inferiore.

Nach MPPT100/20 und MPPT150/35 ist dieser Laderegler der nächste Schritt in Richtung eigener, ergänzender PV-Stromversorgung mit 24V-Akkublock. Es sind 4 Panels mit je 405Wp angeschlossen, die max. Spannung liegt an manchen Tagen über 145V (und bisher immer unter 150V). Ich beabsichtige bei U > 145V eine zusätzliche Last parallel und bei <145V wieder wegzuschalten. Die Parameter habe ich so wie bei MPPT100/20 und MPPT150/35 eingestellt, ich betreibe Blei- und LiFePO4-Batterien parallel. Die aktuelle Stromabrechnung ist nun weiter gesunken, bei einem Netzbezug von erstmalig unter 1000kWh/Jahr.

Very safe and secure, I trust it to safe unattended operation for long periods. Very high build quality. Passive cooling makes it totally silent. You need some reseach or understanding about what type of battery you are charging to effectively use this product. Superb app to controller unit via BT.

ich habe inzwischen alle PV komponenten von victron und ich brauch mir keine sorgen zu machen dass ein gerät abraucht oder mit lautem knall den geist aufgibt. ich empfehle diese produkte jedem weiter der was gscheites haben will! ich habe jetzt noch vom 150/70 auf den 150/85 gewechselt, hier habe ich ein kleines Manko entdeckt, das aber für die wenigsten relevant sein wird: der 150/80 verursacht deutlich mehr (HF) Funkstörungen durch die Regelung. ich würde mir generell eine bessere Filterung dieser Signale an den Ein- und Ausgängen wünschen. Die Gesamtbewertung sehe ich dadurch nicht beeinflußt, da das Gerät das Beste in seiner FUnktion ist, das ich je verwendet habe.
