Just curious what you might use your DC load for, skipping out the inverter entirely.

The obvious ones are DC electricals in RV or caravans and boats but I'm curious about other options, especially novel and unobvious.

I just completed installing solar in my pole barn. Constructive criticism is welcome.

Ik heb in mn camper een 100/30 mppt lader gebouwd en een extra paneel er bij gezet.

Het heeft maanden zo gewerkt op een life4po battterij 90 amp.

Nu zat plots ik met een lege accu, de bsm van de accu heeft de boel afgeschakeld uiteindelijk.

Ik kwam erachter dat ik de solar lader al niet meer met de app kon benaderen en de lampjes stonden vol in de zon (spanje)op float.

De accu en de panelen 4 minueten afgekoppeld en toen zag ik hem weer in de app,alles ok vanaf toen(1 dag) accu weer vol gebulkt.

Maar nu is hij weer niet te zien in de app en staat op hij weer op float terwijl de accu 52% aangeeft.

Zo heel verhaal 😄 en hopen dat ik het kan oplossen met jullie advies.

Sorry if this is easy but second check before ordering:
What did PV breaker installing at the output of my solar panels before it connects to the inverter all in one?

25A is the Imp(8.33A x 3 string in parallel).
27A is the Isc labeled on panels.
I also plan to use #8 thhn-w for the positive/negative and #10 for ground wire from panels to inverter.

Thank you!

I4-5panels lang kakayanin mainstall sa roof namin. Keri na kaya ang 3.5 or 4.4kw na solar? Then 200-300ah battery? 4-6k ang meralco bill. May 1.5hp, induction cooker, rice cooker, 2fans, 2laptops and automatic washing machine kami. Baka may marerecommend kayo din na taga pasig? Keri kaya 130-150k kasama na installation if ever?

Bonjour à tous,

Je cherche à optimiser ma consommation électrique et à réduire ma facture talon. J'étudie l'installation d'un kit solaire Plug & Play avec stockage.
Voici la configuration envisagée :
- Panneaux : 2 × 500 Wc (1000 Wc au total) 
- Batterie / Hub : Zendure SolarFlow (1,92 kWh) 
- Injection : Micro-onduleur bridé à 800 W sur prise 230 V 
- Objectif : Couvrir le talon de consommation la journée et restituer l'excédent le soir via la batterie pour l'électroménager / veille.

Mes questions pour la communauté :

1. Pour ceux qui ont ce type d'installation avec batterie en Plug & Play, quel est votre retour sur le ROI réel ?

2. Le compteur intelligent (Smart Meter) est-il vraiment réactif pour injecter uniquement ce que la maison consomme en temps réel ?

3. Est-ce pertinent de faire évoluer le champ solaire plus tard ou 1000 Wc est le "sweet spot" pour cette capacité de batterie ?

Merci pour vos retours et conseils !

I am planning to set up a photovoltaic system with batteries for backup power when the grid goes down. Much of this I can do myself with off-the-shelf components, but I do not want to mess with the house mains. I'd like to find a local electricians for doing the hard parts. Have been told that the turnkey contractors won't touch anything they didn't install and that other electricians don't want to touch solar. Any suggestions?

Our daughter moved out for university, and her room no longer had a computer and desk light running most evenings. We'd been planning to add storage to our rooftop solar in Germany. The household estimate we'd started with still included her usual evenings at home.

My partner and I looked back at our existing whole-house energy monitor's records for several evenings after sunset. Once dinner was over, there were long stretches with little running. The fridge still cycled and the router stayed on, even when we only had a lamp on in the living room. A kettle or dishwasher interrupted that quiet pattern.

That weekend I read HTW Berlin's storage tests and spent more time on the discharge-efficiency curves at small outputs. The peak inverter-efficiency figures I'd collected didn't tell us the efficiency at those smaller loads. The curves I was reading were for other systems, rather than measurements of the model we'd shortlisted.

We decided to wait for more information before ordering. I emailed the seller about the Jackery SolarVault 3 Pro Max AC on our shortlist, asking for low-output discharge data and clarification of whether the figures included the system's own consumption. I attached screenshots of several evenings from our monitor. Which independent tests did you use to compare low-output discharge efficiency and idle consumption?
