Buying off grid doesn’t mean compromise or an empty wallet. You could select Victron or Synsynk/Deye or buy some box with sockets. We do also provide a wide range of imports to give our clients just what they need and ask for.
As you can see this isn’t the “norm” you have AC in and out protection as well as surge arrestors and breakers where you usually get nothing and is an additional cost. Sadly there is only one MPPT which allows 7200w of Solar to charge the battery at 90 amps. Lets just get the specs down and you can have a read
Configurable AC output. (6.2KW)
Configurable AC input switch over (UPS MODE).
10ms UPS mode switching.
95% efficiency in line mode
Configurable Battery charge and float voltages as well as cut off and recovery for high and low voltages.
Works with and without battery.

For the array, we are looking at around 90amp charging current, which puts the battery within the 280ah range, therefore battery sizes from 200-280ah can be charged at “full speed”.
The nominal 240v to 48v would be a 8 panel configuration nominal (3.6kw) Or 12 panels for max configuration (450w bi facial panels) Power factoring this would be 9.5x 13 = 123 amps at max peak. Therefore you may have some clipping for a few hours a day while boosting winter performance.
The system battery we would recommend is a 27.5kWh for daily cycling which would mean that the system can be ran from 2x15kWh batteries. however there could be room for the 50kWh for those who do not want to cycle down low on the battery capacity and wish to maximise the battery life cycles.

Mounting a wiring.
This can vary from project to project and there are many ways to make an array. With 12 panels you could be looking at an array lay out of 4×3 landscape which would give you a width of 8 meters by 3.3 meters. That’s 8 rails and roof hooks to match. I did not include flashing and hook stands and wiring flashing but the ball park figure should work.
Around £1316.00
The total cost is going to be around £5,516 but you could opt for a different mounting system to knock off a few hundred – We have mini rails if you have a box profile roof…. in fact I think we could drop some of the cost to half to get you underway, and then you could add a second battery and packages without a mounting system will allow you to make your own arrangements..
We would always recommend that you don’t put all your eggs in one basket. A system with one battery and one inverter is not ideal, yes you would have your gen to charge the battery in winter, but at night you would not want to hear a gen running. The inverter does NOT work in parallel with another so you cant use this as a redundancy pair.
