I'm using norsk cable between enclosures

If I mount a weatherproof enclosure vertically with a seal on the lid and fit waterproof glands on the left and right sides of enclosure to connect between lights is this legal Thanks for any advice

Which brands do this form of bucking the solar input voltage to acceptable bus voltage for 400V versions and buck solar input voltage to battery input voltage for the 145v versions..

Based on this explanation will a 145v max model voltronic buck say 40-45v up to 49v for battery input it there is enough current supplied by panels(direct sun exposure)

Do all high PV Input (500V) Hybrid Inverters follow this block diagram where PV input is connected to the HV bus..

are there losses converting 400v to 48-50v battery levels input of inverter, if so what is the loss % down converting 400v PV input to battery levels

As I understand it the 400v PV input is converted to battery input levels by the MPPT, please correct me if I'm wrong. Apparently 400v PV input models do not send the 400v to the bus side after the DC to DC circuit,

I was explaining which battery I needed info on how to shut down BMS and so shut battery standby power off.

Apologies for the Leoch battery discussed here

Hi @Scorp007 or anyone else.. do you know how to switch off battery BMS off to switch battery off completely.

Thank you @Scorp007 you had the answer I needed.

There are no solar panels connected to this setup ATM.

Hi I'm posting photos of specs of Inverter as well as battery, there is no name on the battery ! , I'm hoping someone will recognize the make .

Hi Coulomb, I've been wondering lately if its possible to set a 5 Kv Axpert to AC charge but not activate inverter mode at power fail if house is unoccupied and no one using power in the day. IOW the house owner would have to activate the inverter if the power was out once arriving home, Its pointless for inverter to run if no one is home and needing power.. My fridge manages to keep cold fine during load shedding..

There is no solar charger connected during these tests, the fact that the soft start is reaching 600v with no other input voltage other battery is very concerning, Ive already blown IGBTs as a result... Is there any mod available for the FB of the PWM IC to limit/regulate the soft start voltage..
