The problem with WZRELB “reliable” and XYZInvt inverters is the documentation “instructions” vary depending on where you buy them. You can find WZRELB directions that say earth connection for pc board and output, but then with the exact same model on another site stating not to connect to...

Amazon has some deals on lifepo4 batteries right now. TimeUSB 2 pack for $435. Singles are on sale on many brands for $225-$230 which is well the normal $300+ range. Those 4 panels will power up a good system if you have good sunlight. 4-5 hours should give you 4-5kw of power if you...

Charge controllers have a load lug set. This is for light duty lights at low amps usually. It is not correct to connect these to an inverter. So it is possible to wire it incorrectly. In general, yes you can run both at the same time. In fact, after you are at or near full charge on...

As you increase the voltage as mentioned the cable size can be reduced. Another benefit is less heat or waste in the system. If you reduce resistance less heat is produced. Another way to look at it 3000w/12v = 250amp 3000w/24v = 125amp 3090w/48v = 61.5amp The higher voltage generally...

Maybe try going to the city building dept and request that instead of the fine you pay for the permits for a ground mount solar system. Or at least, refund you the fine after completion of an inspected system. Firefighters prefer those over rooftop systems. Firefighters need to cut large...

You may be limited to the cable size by the controller bus connection. Some of these won’t allow 4-6 gauge wire to be inserted. If you can only insert 8 gauge wire then size your beaker/fuse accordingly. If panels are maxed out at 40 amps but the voltage is higher than 12v the SCC will...

The frames are not powered until there is a short, then it’s doomsday if they are not grounded. Bird turds on panels can cause shorts and fires, hail damage, kids throwing rocks. There are lots of ways to electrify an otherwise safe panel. Agian if you’re in an rv with rubber tires...

Yes

WZRELB “reliable”, XYZInvt ? These have an incorrect wiring scheme in some cases where the case outlet neutral is wired to the circuit board hot and terminal bus hot. When they are wired this way it appears to be a 60v 60v split phase but it is most likely a cross current sending voltage...

There are plenty that explain the risks of high voltage panel arrays. Go back and read them again. For an RV or Auto the rubber tires make it a floating ground situation. A home or cabin with an earth ground system should have all equipment casing grounded as well as solar panel cases or...

He lives in Texas, possibly where there are no building code requirements or a lack of inspectors. A few things to consider, if you are tied into the grid already your system is most likely permitted. If adding panels will require inspections you will need to ground the panels. If...

See this if you haven’t sold the unit. Thread 'WZRELB Reliable Inverter 60v + 60v polarity issue. Ground and neutral have 60v?' https://diysolarforum.com/threads/wzrelb-reliable-inverter-60v-60v-polarity-issue-ground-and-neutral-have-60v.66601/

No problem, it never hurts to open up conversations for better clarity and learn if something is missing from an issue. Or it wasn’t explained very well and should be cleared up. Thanks for the kind reply. These are great inverters and even with this issue people have been running them...

No all you have to do is switch the wires “IF” the outlet polarity is incorrect. I disconnected the ground to prove the center tap split phase was not correct. You can connect the earth ground to this unit if the polarity is correct on the outlet and the terminal bus. There is 0.1v (probably...

Check this out it sounds like you have the same issue. I am building a system like yours and have the WZRELB inverter. https://diysolarforum.com/threads/wzrelb-reliable-inverter-60v-60v-polarity-issue-ground-and-neutral-have-60v.66601/#post-837655

One could also de solder the outlet and re solder the wires correctly then the terminal will read correct. This should have been done at the factory. The factory should send them out with the terminal connections white (neutral), Black (hot), and green (ground) with a red a possible L2...

Yes, I cut the board and case ground to prove a concept. It now has the case and board grounded. It reacts the same and no more than 0.2v earth ground drain. The issue is the outlet (reverse polarity), if you use it while using the terminal bus and earth ground it is not a good idea. It...

Removing the ground will not reverse the outlet polarity which is what switching the wires does. The outlet is not wired correctly. It should not be UL listed, if the neutral outlet is “hot”. The ground disconnect to the circuit board was to disprove the theory that it is was using the...

If you own a WZRELB Reliable inverter you should do a quick safety test for continuity between the terminal bus hot and the case outlet hot connections. If these are not wired correctly you can have a cross feed of power to the neutral terminal bus and if that is connected to earth ground it...

I have made some progress towards my cabin build for earth ground with this inverter brand. I have two of them and they both came wired incorrectly. I’ve made some videos explaining and testing the cross wiring of the 120v outlets. If you own a WZRELB reliable inverter you should check out...
