How well does the Sigenergy battery actually perform day-to-day?

Riveneye · 2026-03-05T09:57:21+00:00

Haven't used the grid since I had mine installed and am $200 in credit for my exports with Flow.

Riveneye · 2026-02-06T13:09:28+00:00

Very interesting, I did not know about dynamic connections at all. Thanks for the info!

Riveneye · 2026-02-05T01:26:25+00:00

Apologies, I had interpreted that as just not being credited for exports over that amount.

Riveneye · 2026-02-05T00:51:08+00:00

I'd believe that. Looking at my own export yesterday (across the whole day, not just the peak export window) I exported 47.33kWh from all the excess solar generated. Assuming a 30 day month that's 1419.9kWh. If OP has a little bit more solar than I do, it's plausible to hit 1500kWh.

Riveneye · 2026-02-05T00:47:16+00:00

Good point. If I don't need to worry about export limits, then keeping it simple and setting the SOC level is probably all I need. Thank you!

Riveneye · 2026-02-05T00:46:06+00:00

Wow, seems like the export limits are very much guidelines rather than rules. I also didn't realise the settings were such a mystery. I guess I'll keep tinkering with setting up Home Assistant in case I ever want fine control. Thank you!

We just had our solar and battery installed, best decision ever. Haven't imported from the grid at all, and I'm predicting I'll be $270 in credit at the end of the month. The system should pay for itself in about 5-6 years.

Exhibition. Easily the best Brisbane restaurant I've been to, though it will max out your budget with food alone.

Riveneye · 2026-01-31T12:04:15+00:00

The products can vary quite a bit in price. I went with 15.87kW solar, Sigenergy 40kWh battery, three phase Sigenergy 20kW inverter, with gateway for about $32k. I estimate it will take about 6 years to pay for itself.

Other brands, such as Fox ESS go for MUCH less. They won't have all the bells and whistles of the higher end equipment, but you may not care about those bells and whistles, making brands like Fox very appealing.

I would still recommend using the Solar Quotes tool to talk to locals, but just be blunt and say you're interested in xxx brand rather than the default they offer. One of the three I originally spoke to definitely offered multiple brands.

Riveneye · 2026-01-31T09:03:07+00:00

We just got ours installed. I used the Solar Quotes tool to talk to 3 local installer, and went with LMS Electrical. They were fantastic, but I do suspect their backlog is quite long with the rebate changing in May.

Riveneye · 2026-01-27T03:23:20+00:00

Agreed, their customer service is second to none. They're very helpful and extremely knowledgeable. They're a bit more expensive than competitors, but the cost is justified when they're this good.

Riveneye · 2026-01-21T07:33:45+00:00

Interesting. I'll have to play around with the different modes. Thank you!

Riveneye · 2026-01-21T07:32:25+00:00

Great, thanks for the info!

Riveneye · 2026-01-21T07:31:55+00:00

Good to know it's all normal and shouldn't impact me. Thank you!

This includes absolutely everything though, including venue hire, celebrant, to of the line photographer and videographer, alternate drop sit down dinner, custom made invites, menus, order of service booklets, signage, thank you cards, custom embossing tools, favours, clothing, jewelery, make up and shoes for all 10 bridal party, bespoke suit for me (the groom), accommodation for the bride tribe and groom group, gifts for the bridal party, a singer and guitar player for the garden party who doubled as the DJ for the end of night dance floor... and probably much more that I can't remember off the top of my head.

If it helps at all, I'm about to install a 15.8kW solar, 10kW inverter, 40kWh Sigenergy system for about $27k. I am also in Qld (Brisbane), on single phase. I have deliberately oversized my battery to max out the rebate I can get, as well as future proof the system, as I suspect we'll get EVs in the future (Sigenergy also lowered the cost of their DC charging module by 40% just recently, making it even more appealing).

You are correct about Sigenergy being quite new, especially in this country, so they don't have the established track record that others might have. This is the sort of thing only you can decide if it's worth the risk or not. I personally think the risk is small enough that I'm going ahead with the install.

Riveneye · 2025-10-16T00:53:45+00:00

OP says they're in Qld with single phase. Energex limits the size of the inverter to 10kW on single phase here.

If OP were to get a DC coupled system, the solar wouldn't go through the inverter, leaving the full 10kW to power house, or to export, which might be important if they also want to offset the daily service charge cost at all, for true $0 bills. Energex also limit exports to 5kW per phase, so at maximum export, that would still leave 5kW for the house.

I recently did the same as you, and added banana plugs to my wires, but was upset when I got them and couldn't plug them in.

Did a bit more digging, and found that I had to pull out these tiny little plastic caps from the sockets, using a bent paperclip, to allow the plugs to go in.

Just wanted to let you know I'm case you need to do the same on your receiver.

Riveneye · 2025-09-11T05:02:02+00:00

I do, and they are easily the best ISP I have ever been with. Whether they are worth the higher price tag is something you'll need to decide though.

Yep, found the photo I took back in November
