Electrical setup

[joe_j_barnes]

Long time ago I asked if this setup was ok but unable to find out parts.

Cleaning out the van today after a long trip away and managed to get eyes on battery.

It’s a hankook 90ah leisure battery connected to Victron Bluetooth with smart charger through a sergeant power system 150 solar panel and streetwise 2000w peak 1000w continuous power inverter

How long can I last off grid with fridge running compressor freezer lights etc?

How could I improve if I wanted to ?

Depends on how sunny it is, in theory, infinite if it’s sunny but if it’s not, who knows. Your inverter, at full chat, could pancake your battery in 20 minutes, you have two options, either store more electricity (bigger battery) or generate more(bigger ore more solar panels)

Thanks Deaky If I don’t use inverter ( had it a year so far ) without need for use how does the rest stack up as it’s a minefield to understand ?

The difficulty in giving you a definitive answer is the solar panel, it’s a variable between 0-150. Worst case scenario with zero output from the solar, you might get a day assuming your battery is fully charged & in good condition. Best case scenario with 12hrs of good sunny weather/day, you could run forever.

I have a similar setup, but no inverter.

In UK summer, I've never had a day when the battery isn't full from solar alone, usually before lunchtime.

In winter, some days there's almost no charge by solar, so EHU is needed to keep the fridge going.

Spring/Autumn - anything can happen!

Of course if I drive at all, the DC/DC charger gets things charged real quick!

Thanks all

I have a roof box which sits above the solar most of time unless am on a campsite then I remove so this effects my possibilities really, I may go down a power bank route as a backup too.
