What you described is simple bypass not grid assist/support.

In case you are still wondering, Multiplus 230V with appropriate settings also works fine with an external autotransformer.

From a post on another site.

Technically, "off-grid" inverter/chargers that support grid assist are generating power in parallel with the grid. So, many POCO's do...

Do you already have the Victron inverters? The 2 120V Victron config can work but you might get significant circulating neutral...

Root cause? hate to be the mean guy in the room, but below is my idea of what the issue is. you can only skimp so much when building...

Don't know your BMS specs but some BMS can control charging and discharging separately. So, perhaps your BMS disabled charging (based...

Lightning could certainly have caused the damage. It's probably a good idea to add a ground rod for the inverter.

The inverter FET's likely shorted first causing over current. But that doesn't excuse the failure of the breaker and BMS to cut off the...

So, after 4 to 5 years of working flawless, the 100 kwh lifepo4 battery caught fire at night and burned our house down. Luckily our...

It's a bit surprising that people are getting caught for single digit watt backfeed. Is it so difficult to maintain a minimum grid load...

I doubt the program requires rooftop solar on single family homes to qualify. Community solar in low income area could work. Kind of...

rooftop solar makes great sense, if the price were about $1/w like it is in the rest of the world

Well I did more testing today. Based on prior testing I adjusted the load shedding so that string 1 sheds at 92% SOC and reattaches at...

It's one of the common problems reported in the Enphase forum.

That UPower is a rebranded PowerJack which is notorious for vastly overrated power capacity. The noisy waveform is due to poor...

It's best to connect Envoy in the same panel to avoid current and future potential Enphase comms issues and the expensive filter.

In general NEC does not officially specify specific UL standards in the codes. Instead the relevant standards are usually mentioned in...

UL9540 is required. Make sure the battery sticker clearly show the specific UL compliance. There appear to be battery vendors that...

Is this an off-grid system? If yes, you can probably pick an off-grid inverter and save money. If no (i.e. on-grid), it would be...
