Here’s a detailed look at some of the best solar inverters without battery (i.e., on‑grid or hybrid inverters run without batteries) from brands like GoodWe, Huawei, Fox (FoxESS), and a note on DJDC — covering key features, pros & cons, and recommendations.
Why Choose an Inverter Without a Battery?
- Cost Efficiency: No need to invest in battery storage — lower upfront cost.
- Simplicity: On‑grid inverters feed your excess solar power into the grid.
- High Efficiency: These inverters are optimized for direct conversion and export.
- Scalability: Easy to later add batteries or expand the system if required.
Top Solar Inverters Without Battery
1. GoodWe
Key Models & Features
- GoodWe offers a wide line of on‑grid inverters (single- and three-phase), including the SDT G3 series. GoodWe+2GoodWe+2
- For example, the GW15K‑SDT G3 (15 kW, three‑phase) delivers up to 98.6 % efficiency, supports dual MPPTs, and has a DC input up to 1,100 V. Solaro
- The GW10K‑SDT G3 (10 kW) offers 98.7% efficiency, IP66 protection (so it’s rugged enough for outdoor installation), and smart monitoring via Wi-Fi / LAN / RS‑485. Solaro
Hybrid Models Used Without Battery
- Some GoodWe hybrid inverters (like the EH or ET series) can be set up without battery, effectively functioning as on-grid inverters for the time being. For example: “Yes, they work without a battery. I installed a couple of them.” Reddit
- This gives flexibility: run just on-grid now, and later add storage when needed.
Pros
- Proven reliability and good warranty support.
- Wide range: from small residential to large commercial.
- High conversion efficiency.
- Smart monitoring and communication options.
Cons
- For hybrid models: some “no battery” setup may need special configuration (depending on model).
- Warranty coverage or service can vary — check local supplier.
2. Huawei (SUN2000 Series)
Key Models & Features
- Huawei’s SUN2000 series is a top-tier on-grid string inverter line. ENF Solar+1
- Efficiency is very high; for example, the SUN2000‑115KTL‑M2 has a maximum efficiency of ≥ 98.6% (400 V) / ≥ 98.8% (480 V). Huawei Support
- Lower‑power model: SUN2000-5KTL-M1 (5 kW) — single phase, dual MPPT, 98.4% peak efficiency. SUN SOLAR
- Higher power industrial / commercial inverters: e.g., the SUN2000-330 kW H2 model offers industrial-grade capacity, 99% efficiency, and 6 MPPTs. SUN SOLAR
- Some smart‑string versions offer natural cooling (fan‑less) and built-in protection (e.g., AFCI, surge protection). ENF Solar+1
Pros
- Very high efficiency — among the best in the industry.
- Mature ecosystem and well-known brand.
- Good for both small residential systems and large utility-scale.
- Integrated safety features.
- Smart monitoring (Huawei FusionSolar).
Cons
- Depending on local stock, some models may be more expensive.
- Some users report “device fault” issues after grid return (according to user reports). Reddit
- More complex to install / configure for optimal MPPT strings (especially for larger systems).
3. Fox (FoxESS)
Key Models & Features
- FoxESS inverters (often branded simply “Fox”) provide both on-grid and hybrid inverters.
- According to local reviews / listings, Fox on-grid inverters reach up to ~98% efficiency. Zarea+1
- Inverter models are available in various power ratings (residential to commercial) and are known for fan-less (silent) operation in some models. > From a Reddit installer: “This inverter is absolutely silent … I have heard … other inverters … give a bit loud fan sound while this is totally silent.” Reddit
- Build quality is often compared favorably to other major brands like GoodWe. Reddit
Pros
- Good value for performance.
- Silent operation (in some models) — good for residential rooftops.
- Reliable, with solid local feedback.
- 10-year warranties are common.
Cons
- Fewer very large industrial / utility-scale options (depending on region).
- Monitoring ecosystems may be less mature than very large brands.
4. DJDC
Reality Check
- DJDC seems to be more oriented toward hybrid inverters. For instance, their DJDC PV7000 6 kW model is a hybrid with a 7,000 W MPPT solar charge controller. Alladin Store
- Another model: DJDC PV5500 Dual Hybrid (4 kW). Alladin Store
- These aren’t purely on-grid inverters; they are designed to support batteries. The “hybrid without battery” use-case may not be ideal or fully supported for all DJDC models.
Caution / Cons
- Running a hybrid inverter from DJDC without a battery may lead to limitations or instability — not all users report stable “battery-less” operation.
- Warranty terms: local listings show a 1-year parts + 4-year service warranty for PV7000. Alladin Store
- Less global support than big brands like GoodWe or Huawei.
Comparison Summary
| Brand / Series | Use-case (without battery) | Key Strengths | Considerations |
|---|---|---|---|
| GoodWe SDT G3 (On-grid) | Pure grid-tie | High efficiency, proven reliability, good support | On-grid only (no storage) |
| GoodWe Hybrid (ET / EH) | Hybrid now, expand later | Flexibility, future-proof | Needs configuration for “no battery”; some setup quirks |
| Huawei SUN2000 | On-grid / smart string | Very high efficiency, wide model range, smart features | Cost, installer skill required, some user‑reported faults |
| FoxESS (Fox) | On-grid / hybrid | Good performance, silent, good warranty | Smaller model range in some regions |
| DJDC Hybrid | Hybrid (not ideal for no-battery) | Cost-effective, MPPT capacity | Not designed / optimized for battery-less mode; warranty/long-term support risk |
My Recommendation
Given your interest in inverters without batteries, here’s what I’d suggest:
- If you want a proven, efficient, and widely supported on-grid system → go with GoodWe SDT G3 or Huawei SUN2000.
- For residential rooftops, GoodWe 10 kW or 15 kW is very solid.
- For larger commercial systems, Huawei’s higher‑capacity string inverters are excellent.
- If you think you might add a battery later → consider GoodWe Hybrid (ET / EH) or FoxESS hybrid, but configure them now to run without a battery. That gives you future flexibility without paying for a battery upfront.
- Be cautious with DJDC if your plan is “no battery”: since their inverters lean hybrid, running them without battery may lead to reduced performance or unsupported operational modes.
- Work with a trusted installer: Make sure your installer has experience with the specific brand and model. Getting MPPT string layout, grid settings, and monitoring config right is crucial.
Potential Challenges & How to Mitigate Them
- Grid Stability: In places where the grid is unstable, an on‑grid inverter may shut down during outages. If that’s a major concern, plan for battery later or choose a hybrid now.
- Monitoring Setup: Use the manufacturer’s monitoring app (e.g., Huawei FusionSolar or GoodWe’s portal) to keep an eye on production and system health.
- Warranty: Confirm local warranty terms. Even if a brand has a global reputation, support depends on regional distributors.
- Oversizing: Use DC oversizing carefully so you don’t overtax the inverter, but also maximize panel usage.
Conclusion
- If you’re looking for battery-less performance, on-grid inverters from GoodWe, Huawei, and Fox are among the best: efficient, reliable, and future-upgradable.
- GoodWe offers flexibility (hybrid ready, but can run without battery), Huawei leads with very high-efficiency string inverters, and FoxESS brings a good balance of quality and value.
- DJDC is less ideal in purely on‑grid scenarios, as their focus is more on hybrids with storage.
