SUNGOLDPOWER 10000W 48V Solar Inverter, Built-in 2 MPPTs, Max 200A Battery Charging, Split Phase AC Input/Output 120V/240V(settable),Pure Sine Wave (BMS COMM) UL1741 SPH10048P

This SUNGOLDPOWER 10000W inverters are great! I have then set temporary on a table but I have been running them for over a month now and I have not had any issues with them at all. They perform very well either as a single inverter or both together in parallel. A single inverter is perfect for your critical circuits like fridge, freezer, lights and normal small appliances like microwaves, coffee makers, air fryer, toaster and such, I even added my 2HP air compressor to the mix and it runs perfect with a single inverter. You do need to make sure that you balance your 120V loads from the L1 and L2 outputs because you only get 5000W per leg (load balancing should be done even in parallel mode). One inverter is all that I need at the moment because I don't have any large appliances wired to my system yet but I will after I add more solar panels and more battery storage and I wanted to make sure that both inverters match so that they play well together and they sure do play very well together. I turned on as many loads that I could including the clothes dryer just for testing and I was pulling around 12000W with both inverters in parallel, that is pretty extreme because we never run all the appliances at once in fact, I tried running the clothes dryer on a single inverter while running the critical circuits and other small appliances like we normally do and it works fine. In conclusion; I really do like these inverters, you can add up to 6 in parallel if you need to, they are pretty easy to set up, the manual is very detailed including wiring diagrams (I recommend downloading the PDF manual because you can just click on the contents menu or do a search and it will take you where you want to), and if you need any help or just have a question, the support team is great either by email or by phone.

This inverter gets the job done!

### Product Review: SunGoldPower SPH10048P All-in-One Solar Charge Inverter The SunGoldPower SPH10048P all-in-one solar charge inverter was deployed to manage a hybrid power system for my workshop, paired with an Eco-Worthy EW-SRB48100-BV2.0 48V 100Ah LiFePO4 battery. Note that for 120V single-phase grid power, a jumper must be installed between L1 and L2; otherwise, the unit powers up but does not function correctly nor provide an error code indicating this issue. Initial operation revealed a charging current limited to 1A DC, significantly below the configured 25A maximum (Setting 28) and the system’s 100A total capacity (Setting 7). This technical evaluation details the diagnostic process, resolution, and performance assessment based on operational data, user manual (v3.0, 41 pages), and correspondence with SunGoldPower support, with the 25A setting reflecting my lab setup’s capacity after initial difficulties. #### System Configuration and Initial Performance The inverter was configured per the manual (pages 23–28) with key parameters recorded on September 18, 2025, : Setting 1 = Uti (utility-first mode), Setting 6 = SNU (solar + utility charging), Setting 4 = 49.2V (likely a 230V typo, adjusted to 120V for US grid), Setting 7 = 100A (max charge current), Setting 9 = 58.4V (absorption voltage), Setting 11 = 58.4V (float voltage, exceeding LiFePO4 norms), Setting 28 = 25A (max utility charge), Setting 33 = pyl (Pylontech BMS protocol), and Setting 68 = 0 (single-phase with neutral). The battery, initially at 51.1V (~20–30% SOC), exhibited balanced cell voltages (3.19V ±0.007V) and normal temperatures (34.4–35.6°C), per BT_BMS app data. Initial charging showed a 1A rate, suggesting a BMS or algorithm restriction. A breaker trip occurred during a BMS bypass (Setting 32 = SLA, Setting 8 = USER, RS485 disconnected) with the default max charge current, but this was later identified as a lab setup error, providing a useful observation of excessive current draw rather than a fault in the battery or inverter. #### Troubleshooting and Resolution Diagnostic efforts included adjusting Setting 01=SUB and Setting 06=SNU per support’s recommendation, which had no effect with the initial Uti and SNU settings. The manual (page 23) notes BMS communication via RS485 (Setting 32 = 485) overrides user settings, suggesting a limitation. Support (Penny, @sungoldpower.com) requested scrolling screen videos and settings images, hypothesizing BMS control. No Alarm 58 (BMS communication failure) was observed. Adjusting the max charge current to 25A (Setting 28) after the “BMS bypass” was enabled resulted in a successful 100% charge to 58.4V, indicating the default setting caused the observed 1A current draw. However, a “discharge and recharge” test with 485 communication (BMS enabled, Setting 32 = 485, Setting 33 = pyl) reverted to 1A draw. Today, September 19, 2025, I changed Setting 01 from Uti to SUB (mains power prioritizes load before charging). This restored the 25A charge rate, with the battery at 52.79V (DC voltage) and reached 100% charge. A planned “discharge and recharge” test (simulating a power outage)constituted of, running a load (heat gun 1200w) and after turning the load off, I connected lab power to the inverter and turned the AC breaker on. The inverter sensed the AC and went into charge mode at 25A DC to the battery. (A Pass) #### Performance Assessment The SPH10048P demonstrates robust performance with a 48V 10kW capacity, supporting grid-tied and off-grid operation (manual page 5). The LCD provide real-time data (e.g., 0.8A/0.3A currents pre-adjustment), and the system handled lab loads effectively. The BMS dependency introduces a potential limit; the manual lacks clear communication troubleshooting guidance. Firmware updates via USB-B (page 34) are recommended but not detailed. Support was responsive with requests for media and suggestions. #### Conclusion Rated 4/5, the SPH10048P is a capable hybrid inverter for technical users navigating BMS challenges. The 25A charge was achieved by adjusting Setting 28, with Setting 01=SUB today resolving the 1A issue post-discharge, aligning with a 50A lab setup recommendation (manual page 14). Recommendations include clarifying BMS troubleshooting in the manual, optimizing Setting 11 to 54V, and enhancing firmware. The recent discharge/recharge test and subsequent 25A charge mode confirm stability with Setting 01=SUB. Contact SunGoldPower( [email protected] ) with logs if needed. As of September 19, 2025, the system is operational at 25A DC charging.

This is the second Sun Gold Power inverter I have purchased. I really like the app that you can download for the unit. I also like that I can add 5,000 more watts of solar panels without needing to buy a second charge controller.

Bulletproof ,love it works great.

I purchased this inverter after watching Will Prowse review of it. This was an upgrade from my EG 43 kW inverter. I wanted something that would run 240 split for my welder. While I have not upgraded to the welder just yet, this inverter is working beautifully. I don’t get any flicker with the Lowe’s that I have. I’m running currently with only four eco-worthy 40 V batteries. Have not had any codes. There are a lot of selections to choose from, but I had Grok help you through it and it works out great. I did struggle with setting the parameters for the lithium ion batteries however I realize that the batteries themselves were the ones that were causing a problem telling me that they wanted to choose its own parameters. So either way. It’s a sexy freaking machine. Seems to be doing fantastic. I’ve had it running flawlessly now for just three or four weeks. I’ve got 10 solar panels on one of the strings, I actually have to divide them up and put them on the both MMPT‘s. I just haven’t done that yet and the batteries have been great too. A better review with more interesting things to say, but I have to say I’m very happy with the unit. I went ahead and bought it, especially with everything going on in the world in the oil issues and probably future embargo’s coming. I figured let me go ahead and get this now. I don’t regret it in the least.

I noticed it gets overloaded with small appliances easily. I need more batteries to update my review. So far so good for 5 months. 3 stars because at this price it should come with battery cables

We love our inverter. we had a couple of technical questions and received immediate response from customer service.They were very competent and well spoken.
