Hi everyone,I recently faced some communication problems between my Sunsynk inverter and the monitoring app. After some testing, I found a few practical steps that helped me:

1. Check all cable connections – loose RS485 or Ethernet cables can often cause intermittent errors.

2. Firmware update – make sure your inverter firmware is the latest version. It solved many unexpected bugs for me.

3. Network settings – verify your local network allows the inverter to communicate with the app; sometimes firewall settings block it.

4. Restart devices – a simple power cycle of the inverter and router often clears temporary glitches.

Hope these tips help anyone facing Retro Bowl 26 similar issues. Does anyone have additional troubleshooting advice or best practices for Sunsynk systems?

Hello Sunsynk community,

I am operating a Sunsynk PolyTrack hybrid inverter + lithium battery system with a BMS and have noticed a discrepancy in SOC between the values ​​displayed from the battery BMS and the inverter, especially after deep discharge and fast charging cycles from the PV.

Practical Observations:

The SOC from the battery BMS is usually 5–10% higher/lower than the inverter.

After full charge, the discrepancy decreases but doesn't disappear completely.

There are no BMS communication errors.

I'm using a Sunsynk inverter with a lithium battery and have noticed that the SOC reading is unstable during daily use.

Specifically:

• SOC fluctuates rapidly in short periods.

• When the load changes, That's Not My Neighbor SOC jumps erratically.

• The battery still has charge, but the system reports it's nearly empty.

My current setup:

I would like to start a technical discussion thread focusing on the design and optimization of solar power systems using Sunsynk hybrid inverters, particularly the coordination between PV array, battery storage, and inverter in real-world operating scenarios.

Regarding inverters, Sunsynk hybrids are highly regarded for their ability to manage multiple sources (PV, grid, battery, load) on a single platform. Correctly configuring parameters such as charge/discharge current, grid support, priority mode, and export limit significantly impacts system efficiency and lifespan.

As for batteries, I find Sunsynk compatible with many types of lithium batteries (LiFePO₄), especially when the BMS communicates via CAN/RS485. However, choosing the right battery capacity to match the inverter's power and PV output remains a crucial consideration to avoid deep discharge or excessively rapid charging over extended periods.

Regarding PV arrays, correctly calculating the number of strings, DC voltage, and MPPT range is key. In practice, I've seen many…

L’autre jour, en regardant un reportage sur la préparation de la CAN, j’ai repensé à une discussion que j’avais eue avec un ami qui travaille dans un petit club local. Il disait que, pour les grandes compétitions, la stabilité des partenaires joue souvent un rôle énorme, parce que ça évite de repartir de zéro à chaque édition. Du coup je me demande : pourquoi la CAF choisit-elle de garder le même partenaire officiel pour la CAN 2025 ? Quelles sont leurs vraies intentions derrière ça – stabilité financière, image, organisation, ou peut-être quelque chose d’autre ? Je suis curieux d’avoir des avis et des expériences.

Je viens de m’inscrire sur une plateforme de paris et j’ai vu l’offre “Mercredi x2”. Je me demande si c’est vraiment fait pour les novices comme moi ou si ça nécessite déjà une certaine expérience pour en tirer profit. La semaine dernière, j’ai tenté de suivre la promo et j’ai un peu été perdu avec les conditions et les mises optimales. Est-ce que vous pensez que ce type d’offre aide vraiment les débutants à comprendre le fonctionnement des paris, ou est-ce plutôt un avantage pour ceux qui connaissent déjà les stratégies ?
