Was done. This inverter went in for repairs at some stage and I suspect it came back faulty. The neutral bond was not such a topic then. Why is the Deye firmware update not as easy as the Sunsynk one?

Gents, We have this inverter that does not do a neutral earth bonding when the municipality power goes off. It does not give 230v as it is supposed to do. It has the right relay in and it is correctly wired. Anybody has a fix for this problem?

Gents, I've had this inverter in use for a long time now. I have 4 off 2.4kw Pylontecs installed with it and 14 off 450w solar panels looking east and west. I want to use it to draw the least municipal power. Please post your settings so I can look at it. Regards, Johan

Some time ago I bought portable 200w solar panels from Outdoor Warehouse. I am camping now in the Kruger and don't get more than 80w in bright sunlight from it. The challenge is my normal caravan fridge consumes 130w. Is it normal and what I can I do to get 150w from it? In a week's time I'll be in Tzendze where there is no power. I am now looking at buying some 4 x 100w glass solar panels to get to the watts required. My intention is to charge a Gizzu Challenger Max 1000W / 835Wh Ups Power Station Lifepo4 from the solar panels while it powers the caravan fridge.

I replaced mine with a 50a car battery and a 5a Victron charger. I reckon it should give 10 years reliable service. The pathetic 1a charging board which you find in most all devices is responsible for most of our trouble. A dead motor gate can lead to a lot of problems - think about it when you are 70 plus.

My son in law had a Deye 8kw installed on a lease. Company guy told him they’ve got a 1000 installed units. If there is any trouble they swop it out immediately. Suppose its horses for courses.

My setup is so much easier with a transfer switch from the mains to the generator. I have a choice on where to send the generator output then. If I need to charge the batteries from generator (= very expensive) I'll need to reduce the battery charging amps. I've changed my Sunsynk setup to grid charge the batteries to 99% soc at 17h00 (dependant on usage and cloud cover - it also helps to use eskom and not batteries with evening meal preparation). Also to 30% soc at 02h00. Got rid of nuisance trips when the family is visiting. It uses about 3kwh per night. I must admit that I'll miss eskom when they go on stop. QED

A transfer switch of sort is a must. And forget about charging at 40a. Determine the max amps your gennie puts out and charge at 1/2 of that. My 6kw gennie battles to do 13a. Your rig needs a lot of amps for charging. I don’t know if you can set it up for charging batteries from a gennie. Otherwise it will just trip on overload. I don’t know if the gennie can be allocated just for charging - seems pointless to me. It must be able to supply your house as well. Then you can carry on when the inverter is down. I also have a 8kw Synsynk with a seperate generator. But I only set it up to run my house. If one is really serious about this you probably need a 16kw generator.

On a farm you pay for the transformer (and size) supplying you It is in your own interest to keep your consumption as low as possible. Keep in mind Eskom might fail 100% in future.

The best way to go about this is to start measuring amps on the pumps. Startup as well as running amps. Don’t consider kw when looking at inverters in this case - look at the maximum amps. Borehole pumps pull ridiculous amps when starting - my 2.2kw uses up to 35 amps to start up. It has tripped my 8kw inverter a few times. My system was installed before I went solar and now it is not cost effective for me to scale down. My 2.2kw pump has an output of way too much 15kl per hour pumping from 65m. But it is what it is. You must look at all the options like solar and variable speed controllers (to minimize startup amperages). With solar pumps you don’t need inverters. You must know how much water you need per day. It might be more cost effective to increase your container sizes - that can reduce pumping rates but also serves as emergency when pumping goes wrong. Why do you need a 3kw pump? Is it a 3-phase system? It is more cost effective to reduce your electrical consumption than trying to supply an oversize solar system. Dwellings for example could each have their own JoJo tank and small pressure pump. Instead of running a pressure pump 24/7 you can also look at a header system - with many mines (for example) closing shafts they should be on the 2ndhand market. You have the advantage of expenses being tax deductible.

I think my pool look beautiful. My swimming pool pump runs just from solar - but I switch it off when solar is low due to rain and clouds It is a 1.5kw pump with a 70kl approx. pool. It is managed by a sonoff that also measures the power consumption and running hours. In March I ran it for 138 hours with 17 days where it did not get to 5 hours for the day. It was on stop for 3 days. It is set for 7 hours per day. The coming winter I’ll set it up for 4 hours per day. Last winter it was eskom set to run for 4 hours per week. I had it remarbelite for this season so it needs tlc. We swim every day when the weather is good - in summer that means about 18 days per month 😂 It is heated to 30 degrees C - depending on the sunlight. With the weather turning now I’m thinking to cover it for winter. My pumping system is dual purpose - cleaning as well as heating. You did not mention why you want to minimise pump hours.

I am shocked by these reports. My 8kw Sunsynk has been going well for two years now with no problems. If you want to sink any brand it must get a bad name from South African consumers. There are plenty of car manufacturers who can vouch for this. I wish Sunsynk well for their venture into Australia as they don’t have our patience. Oh, and the Aussies read our forums. Keith would do well to take action in this market. My brother had a not so good repair experience with Deye recently - will I recommend it. Obviously not …

I suggest you verify the voltages with a good multimeter. Is the builtin charger in your inverter really good enough for what you want from it. I recently invested in a very expensive (for me) Victron ip22 30a 12v charger to do maintenance on all my batteries - it was an eye opener for me. Its got a bluetooth app where you can see what it does.

4 off US2000b pylontechs - now going for 4 years in use. I don’t restrict usage at night as the setup changes over to Eskom (when available) when the battery shuts down. My batteries are set to charge only from solar. I ticked the “activate” in the Battery setup - wasn’t done before. I have a 8kw Synsunk inverter. I don’t dig into the battery cell info like @Nexuss does.
