Re: AGM for home storage?

AGMs can be very long lived and reliable: a. I had a 1000AH/12V set up on my barge in France. After 8yrs, they are in almost perfect condition. Average cycle depth only 23%. 4.5kW inverter. Excellent solar MPPT plus engine 4step temperature controlled charging plus 120A mains charging (when mains av...

Re: OpenEVSE Charging Station any Users?

Lobster & Jonescg, Just a note about the OpenEVSE. If the advanced one, the temperature sensor is on the LCD panel. If you wire it well, the only heat generating object is the AC:DC converter (aforementioned for RFI). If you use the box flat- as shown above- the heat of the converter artificially in...

Re: OpenEVSE Charging Station any Users?

This is the unused box.
Will dig out photos of the 3Ph unit. As I already had a Type2:type2 cable, I mounted a Type2 socket on the box rather than have a flying lead.

Re: Single phase charging

Hi Matt, Those figures agree closely with my experience. However the 6A three phase ones are definitely odd. I'm wondering if the heat pump was running to condition the battery? Heat pump can draw over 3kW and it runs directly off the traction battery. Since my original post, I did implement two Lit...

Re: Sumry Inverter-Charger in Caravan

Correct.

Max current drain, both on full bore is 135 to 145 amps when the cells are fairly well charged (about 80%).

Load on the inverter is approx 70%. Efficiency around 90%.

These units have a high COP (which is the main reason I chose them).

Regds,
Dave

Re: Sumry Inverter-Charger in Caravan

For those with a Sumry or contemplating same:

I now have my 5kVA unit running two LG split air conditioners. Each is 6,000W and the SUMRY handles both with ease, even on maximum cooling or maximum heating both running together.

The Sumry is driven by 8x AVASS bus cells.

Re: Sumry Inverter-Charger in Caravan

Hi Jordan,
I have been able to communicate with the RS232.
Can do some basic stuff and read voltages etc.
Hary has also been able to do this.
But neither of us is actually using it.
I am using the remote control panel and also have a very large DC contactor on the battery side.

Re: Is anyone using an arc welder with an offgrid system

Not sure you understand my setup. The house is bonded in the normal manner. The grid does NOT connect to the inverter in any way. In other words I am NOT using the grid input (which is not connected) nor the ATS nor the inverter's charger. Things connected to the inverter are totally separate from t...

Hi Jordan,
Yes, the output is totally floating (insulated) from everything else so there is absolutely no problem.
Also, my unit continues to function beautifully.

Excellent range figures! A 64kW battery sure makes it all very doable.
Have you noticed how things go with a stiff headwind?

Re: On tow?

I realise the Q is in the Hyundai forum. However FYI, the Renault Zoe can only be towed if the battery is flat. Else it must be flatbedded or towed front wheels up. Information in the user handbook. So, not all vehicles will be the same.
