We were called to clean up an installation, some fly by night installer blew up 1 x Lux power unit, and left the other standing. We found some shocking things:

1. No Surge Protection

2. No PV DB, no fuses, do DC SPD

3. No Battery Isolator

4. AC Breakers were being used on customers PV String, two suppose to come down one was left in the roof for Santa Clause 

5. They wired the luxpower directly to the DB with no input/output breakers or changeover

6. They somehow thought that the PV strings must also be wired directly to the battery.

7. In correct cabling being used every where 

8. Tobo batteries - BMS does not work with Luxpower 

9. Panels were not secure on the roof, 1 string was wired to the inverter, the second was left with cut cables in the roof

Long story short the first installer was suppose to run 2 plots with the 2 x Lux units in parallel, but they wired it series!!! Well that was a disaster and one blew up. Funny though how their website claims to have done over 4000 installs ?

We put in a Sunsynk 5kw Inverter and 5kw Battery for one plot and tried to run the other with the Lux and Tobo batteries. The Lux power soon became faulty its seems input and output relay/contactors failed.

When we were done: (Lux power and Tobo is now decommissioned)

Good man 🍻It's harder to clean up a mess than just get it done the 1st time right . There will be much more stories like this in the future.
